Heroes

Agents in General

The main agents of Odd Squad across all three seasons.
Not pictured: Agent Osmerelda Kim and the Little O.

Members of Odd Squad, the organization founded to stop oddness. Every employee is a child.

• Action Duo: The Investigation agents are teamed up.
• Badass Adorable: They are very good at their jobs and are very precious.
• Badass in a Nice Suit: Most Investigation and Management agents wear suits.
• Bunny-Ears Lawyer: The characters are very quirky, yet all competent.
• Chaotic Good: More than a bit weird in personality, organization, and techniques, but are definitely good people tying to stop odd and help others.
• Crippling Overspecialization: While skilled at fighting oddness in the field, many Investigation agents have a lack of skill in other areas covered by different departments, such as Maintenance/Transportation and Science.
• Hero of Another Story: While the only characters to really get focus on their cases are the main characters, episodes pop up here and there to show what the other agents work on.
• Kid Detective: Well, they're all kids, and must do some detective work in order to stop oddness.
• Little Miss Badass: Most female agents are this to some extent.
• Grade-School C.E.O.: All precincts are run by a Director in the Management position. How young they are can range from infancy up to the age of 12.
• Platonic Boy/Girl Heroes: Basically every set of partners that are the opposite gender.
• Red Is Heroic: The main characters, the Investigation department, are associated with red.
• Riddle for the Ages: The series intentionally leaves it a mystery as to whatever happened to the agents' parents and what their home lives are like.
• Teen Superspy: Preteen, but close enough. They aren't exactly spies, but they are agents who solve mysteries/crimes.
• Theme Naming: Every agent's name begins with the letter 'O'. The only exception ended up a villain after his Face–Heel Turn.
• True Companions: They are pretty much all best friends and are always there for each other.
• Workaholic: They are rarely ever seen not working.

Season One

Agents

Agent Oprah/Ms. O

^{Click to see her as the Big O.}

Played by: Millie Davis

Ms. O, formerly Agent Oprah, is the head of Precinct 13579. She delivers cases to agents who then go on their way to solve them. She is tough, grumpy, short-tempered, and easily angered, but she will always lend a helping hand to those agents who struggle. She used to have Agent O'Donahue for a partner before he officially retired. In the Season 2 finale, she gets promoted to the Big Office and becomes the Big O.

Tropes applying to her characterization in Odd Squad: Mobile Unit should go here.

---

• The Ace: Really, there's little to nothing that this girl can't do.
• Affection-Hating Kid: In the beginning of Season 1, Ms. O never gave any affection to her agents due to being a Bad Boss, to the point where, in "Reindeer Games", she had to be instructed by Oscar how to act, and ended up being awkward at every attempt she makes. She becomes more affectionate in Season 2 onward.
  Ms. O: OCTAVIAAAAAA!!!
  Octavia: (as papers fly everywhere) Ah! What did I do? Am I fired?! I’ll pack my things.
  Ms. O: No, I just came by to say I, um, uh...uhh, think you’re great! (gives an awkward smile)
• The Ageless: She worked a fruit stand before joining Odd Squad back in the year 1870, and still looks 7 years old.
• Ageless Birthday Episode: It's Ms. O's birthday in "O is Not for Old", but her age is never revealed. Considering she can control her aging, though, it's likely that she just decided not to age up a year and stay the same age.
• The Alcoholic: Though G-rated, her thing for juiceboxes is treated this way.
• Alternate Self: As revealed in "Ms. O Uh Oh", Ms. O has one that came from the past (specifically, December 17). In "Ms. O Uh-Oh", as a result of it coming to life, she's driven out of her office due to the looming threat of a timetastrophe if the two Ms. O's happen to see each other.
• Beehive Hairdo: In "Whatever Happened to Agent Oz?", the black hole Oz accidentally creates manages to make Ms. O's hair like this, loosening the tight bun she usually wears.
• Big Eater: She drinks a thousand juice boxes as her daily rations, but cuts back to one hundred by Season 2. Her Mirror Self has just as big of an appetite, only she eats large portions of food (specifically, egg salad) rather than drinks.
• Black Boss Lady: Is the leader of Precinct 13579 (later Odd Squad as a whole), and is dark-skinned.
• Character Development: Over time, she went from a Mean Boss who often yelled at her agents and had a short temper to a Benevolent Boss who was more supportive of her agents and often helped them out. This was largely in part due to critics who often complained about her yelling and her overall attitude, despite the fact that as a character, she is meant to parallel real-life bosses. In the Season 2 premiere, she delivers a Take That! to said critics.
  Ms. O: If you're always yelling, that's all people think you do, and they don't see that there's a lot more to your character.
• Clueless Boss: In "Life of O'Brian", Ms. O never hears about the bullying going on with O'Brian and the other agents. Justified, as Olive was explicitly told that telling Ms. O about the issue would lead to disastrous consequences from O'Brian.
• Competition Freak: Ms. O becomes one in "The Jackies", as she sends all of her Investigation agents onto the field in order to seek out and eliminate oddness. It's justified by the fact that her precinct hasn't won a Jackie Award in millennia.
• Compressed Vice: Ms. O becomes quite narcissistic in "Flatastrophe". She has a cube with her favorite "memories" on it, which is mainly comprised of her various face expressions, and when Otto takes her jackalope artwork, she complains that she has nothing beautiful to look at before looking at herself in the mirror. While Ms. O has been known to be selfish before, she's primarily portrayed as being a Jerk with a Heart of Gold who is tough but fair on her agents, and rarely displays any "It's All About Me" traits.
• Everyone Calls Him "Barkeep": She is almost always referred to as "Ms. O", which is a title used for female Odd Squad Directors. Only few have referred to her by her first name, such as O'Donahue, Oscar, and Orville, and it's implied that only those close to her (professionally or personally) can refer to her as "Oprah".
• Extreme Omnivore: In "Agent Obfusco", Ms. O eats Olive and Otto's badges to check if they're expired. However, the badges also double as phones, meaning she basically ate part of a cell phone.
• Fangirl: Of the boy band Soundcheck.
• Grade-School C.E.O.: Like everyone else in Precinct 13579, she is of elementary school age, but she runs the precinct.
• Greed: Ms. O has a juice bar in her office that is only for her. Anyone that lays a finger on it or its contents is liable to receive a No-Holds-Barred Beatdown.
• Heroes Fight Barehanded: In "Oscar and the Oscarbots", it's implied that Ms. O took out a bear with nothing but her bare hands and her martial arts skills.
• Hidden Depths:
  • She's a skilled piano player.
  • Ms. O is a surprisingly apt mechanic, having repaired a car's carburetor, timing belt, and pistons.
• I Need a Freaking Drink: She is notorious for her love of juiceboxes and noticeably gets irritated when she goes without them. It is often likened to alcohol addiction:
  O'Donahue: Still on the juice, huh?
  Oprah: I can quit when I want.
• Lady in Red: Ms. O wears an elegant, sequined red dress in "The Jackies".
• Jerk with a Heart of Gold: Most definitely so. She can be harsh, but means well.
• Kung-Fu Kid: Ms. O is one, being strong enough to break multiple cinder blocks and take down a bear. In "Oscar and the Oscarbots", it's implied that she trains often at a dojo situated inside Precinct 13579.
• Little Bit Beastly: Part of Ms. O's transformation in "The Odd Antidote" includes a lion's tail and a pair of antennae.
• Little Miss Badass: Do not challenge her. You will lose.
• Mean Boss/Benevolent Boss: Used to be the first, but gradually turned into the second.
• Mirror Self: In "O is For Opposite", she accidentally releases her reflection from a Magic Mirror and becomes trapped in the mirror in their place. Her reflection is overly sweet, gives her agents Affectionate Nicknames, and despises juice boxes.
• Named After Somebody Famous: Obviously Oprah Winfrey. Her old partner O'Donahue is this too (Phil Donahue being someone who works with Oprah).
• No Indoor Voice: Tends to yell a lot. By the second season, she tones it down.
• Not Quite Flight: She is capable of gliding by using wing flaps on her suit.
• Not So Above It All: Like Otto, Ms. O loves Soundcheck's music and gushes over it.
• Older Than They Look: She is 231 years old, but still looks like a child.
• One-Letter Name: Only known as Ms. O. Justified, as "Ms. O" is the title given to any female Director.
• One-Woman Army: She's shown to be capable of taking down monsters and armies single-handedly.
• Pintsized Powerhouse: She's so strong she can cut an orange cleanly in half.
• Purely Aesthetic Glasses: Ms. O has a pair of reading glasses that she is seen wearing twice in "How to Interrogate a Unicorn", but hasn't worn them at any point beforehand, which would imply that they are simply for show.
• Purple Is Powerful: She's the leader of the precinct, far and away the strongest of the cast, and she and her department are signified by purple.
• Rank Up: She gets promoted to the Big O in the Season 2 finale.
• Really 700 Years Old: She is over 200 years old, and has the ability to control her aging.
• Reasonable Authority Figure: Beneath all that yelling, at least.
• Riddle for the Ages: Just how old is she?
• Significant Birth Date: Her birthday is on November 30, 4 days after the initial premiere of the series.
• Tiny Tyrannical Girl: Yells at everyone, and is one of the shortest in the cast. Becomes downplayed in Season 2 onward as she becomes a Reasonable Authority Figure and tones it down. And gets taller to boot.
• Took a Level in Kindness: Her yelling roles became less and less starting in the second half of Season 1, and she became more supportive with the agents. This is lampshaded in the Season 2 premiere and functions as a Take That! to critics who hated her due to her constant yelling.
• Trademark Favorite Food: Loves juice boxes so much she can be bribed with them.
• Vague Age: She looks like a typical child, but flashbacks and lines of dialogue reveal she's at least 200 years old. But it's never revealed just how old she is, and she sure doesn't plan on telling anyone.
• Villain in a White Suit: Inverted — as the Big O, she wears a predominantly white suit, but isn't a villain.
• Winged Humanoid: In "The Odd Antidote", Ms. O gradually turns into one, but doesn't use the wings for flight.
• Wolverine Publicity: She is the only character to appear in most, if not all, promos for the show across all three seasons, and as such, generally serves as the face of the show. This is justified, however, as most of the core cast switches out every season while she stays behind.

Agent Olive

Played by: Dalila Bela, Isabela Moner (pilot)

^{Click to see her in the pilot.}

^{Click to see her as an Odd Squad Director.}

A 12-year-old veteran agent of Odd Squad. She used to have another partner before she had Otto; it was unclear whom until "Training Day". Despite being no-nonsense, serious, and often full of snark, she has a soft, caring heart.

• Absurd Phobia: She is not a fan of pies. This is justified, as she has a good reason. One OddTube episode reveals that she's attempting to get over the fear.
• The Ace: She is exceptionally good at what she does to the point that she is idolized by other agents and is known among them for her work.
  • Broken Ace: The Todd thing hurt pretty hard.
• Affection-Hating Kid: Zig-zagged. She doesn't take too kindly to Ms. O (or whom she thinks is Ms. O, anyway) pinching her cheeks in "The Briefcase", but is fine with giving people hugs and other forms of affection. Similarly, she also hates being called "cute" and other endearing terms.
• Character Development: Throughout Season 1, Olive begins to loosen up and learns to not take things so seriously. She also begins healing from the trauma she experienced fighting off Odd Todd's pienado starting in Season 2.
• Cloudcuckoolander's Minder: She often keeps the energetic Otto in line.
• Cute, but Cacophonic: Make no mistake, Olive has her adorable moments. But when she screams, hoo boy, is it loud.
• Does Not Like Spam: Dislikes pies. She has a very good reason.
  • Also hates the egg salad pizza combination that Delivery Debbie and Delivery Doug come up with, to the point that eating just one bite makes her feel nauseated.
• Dreadful Musician: Averted. Albeit she doesn't get to sing much, Olive is quite the proficient vocalist.
• Fangirl: She loves sports, Coach Roberts, Santa Claus, and Shmumberman. Her seriousness immediately drops whenever she interacts with them.
• Gamer Chick: She slowly becomes one in "Game Time" through practice playing Robo-Blast-Bots at the Shmumbercade in order to rescue Otto.
• Grade-School C.E.O.: Becomes this in the Season 1 finale alongside Otto. After the events of The Movie, she goes back to leading her precinct.
• Hidden Depths:
  • She is a frequent patron of Club 24 and is quite friendly with Tony the Bouncer — quite surprising, considering that part of what we see of the nightclub is a long line of adults who are nowhere near her age.
  • While she is initially shown to hate Soundcheck in contrast to her partner, she eventually comes to like them by "Disorder in the Court", having attended one of their concerts. The Movie would later establish that she has a love/hate relationship with the band. "Soundcheck Part Deux" would also confirm that she hates the music genre of pop, not just Soundcheck.
  • "Life of O'Brian" reveals that Olive knows quite a lot about laser chickens. Not so much about their eggs, though...
  • She also knows how to operate the tubes, despite working in the Investigation department and having never worked in the Maintenance/Transportation department.
  • As shown in "Fistful of Fruit Juice", she loves cleaning, and states that she loves when dust gets in her eyes and makes her throat burn.
  • While she is well-known for her athleticism, in "Trials and Tubulations", she has a conversation with Otto about enjoying walking as a form of exercise, encouraging him to take it up by suggesting he start using walking sticks.
  • "Oscar the Couch" implies that she's quite skilled at hypnotizing people, but not so skilled at snapping people out of hypnotism.
  • Numerous episodes, as well as The Movie, reveal that she is both a Badass Driver and an Ace Pilot — she can not only drive kiddie cars and makeshift carts, but can also pilot an ice-cream-truck spaceship with ease.
• Huge Guy, Tiny Girl: She is shorter than Otto in the show, but in the original pilot, it's the inverse, with her being the taller one.
• Jerk with a Heart of Gold: While she can be harsh, she really does care for both Odd Squad and her clients.
  • Is also clearly fond of Otto and despises when he's in danger; see the episode where he was trapped in that arcade game and at very real risk for disappearing forever.
• Leader Wannabe: Her goal is to become an Odd Squad Director in the same vein as Ms. O. While "The O Games" showed her becoming one for a day as a prize for winning the eponymous competition, she eventually succeeds in becoming an actual Director in the Season 1 finale, being transferred and promoted to the precinct in the next town over in place of Orville.
• Little Miss Badass: One of Odd Squad's best agents who can also hold her own in a fight.
• Little Miss Snarker: Being a Deadpan Snarker comes with being the Only Sane Man. A lot of her reactions to things are full of snark.
• Living Legend: From Season 2 onward, she's seen as a legendary agent by others who know of her feats and how she rose to eventually become a Director. It helps that she's one of the first main characters in a show that (at least some) agents know about and know that they star in.
• Mama Bear: Can act this way towards Otto at times, such as when fretting over leaving him in Headquarters alone while she heads out for her day off in "Captain Fun".
• Mr. Vice Guy: One of Olive's vices is her tendency to become smug and cocky if she believes that she's correct or if she thinks that something will go well. More often than not, it will backfire on her.
• Neat Freak: Implied in episodes such as "Trials and Tubulations", where she isn't necessarily thrilled about covering herself in mud to avoid laser chickens' detection, but does so anyway (and ends up less dirty than Otto).
• Only Sane Man: Oscar and Otto are easily flappable, and so she often takes this position.
• Passionate Sports Girl: In most sports — you name it, she loves it.
• Platonic Boy/Girl Heroes: With Otto.
• Plucky Girl: Borders on Determinator.
• Put on a Bus: Leaves in the first season finale to be a Director for another precinct. Dalila Bela would later have a voice-only cameo in an OddTube episode and star in The Movie before officially departing from the show.
• Rank Up: Is promoted to the Management department and becomes an Odd Squad Director of a neighboring precinct in the Season 1 finale, along with Otto.
• Regal Ringlets: Her hair is tied in a loose corkscrew ponytail. Unlike most examples, however, she isn't royalty, nor does she act regal.
• Rookie Male, Experienced Female: Olive has been an agent much longer than Otto has.
• Savvy Guy, Energetic Girl: Gender Flipped here. Olive is the experienced and calm one to Otto's new and energetic.
• Shell-Shocked Veteran: She becomes this after the pienado.
• Shrinking Violet: She was shy as an agent-in-training and had a huge lack of self-confidence. The shyness stuck around when she became an agent, but was dropped entirely when her old partner attacked.
• Stereotype Flip: The main reason for her creation as a character was to depict girls as being just as powerful and strong as boys. This is especially prominent throughout Season 1, where she is given some of the top billing as a main character in contrast to Otto, who is also a main character but has the least characterization of any of the other three main characters in the season's core cast.
• Textile Work Is Feminine: While it's not shown onscreen, Olive is quite the skilled seamstress, having sewed multiple Burly Bears uniforms.
• Tomboy: Very much so. She would rather wear pants than a skirt even if the latter is mandated in her department's dress code, she despises princesses, and enjoys sports and reading comic books.
• Trademark Favorite Food: The OddTube episode "Interview with Olive" reveals that as an Odd Squad Director, her signature drink is water, which fits with her "plain" food preferences (such as cupcakes with no frosting).
• True Companions: With Otto.
• Why Did It Have to Be Pie?: She is deathly afraid of pie to the point where she will scream if she happens to see one. The episode "Training Day" explains this fear, and she eventually goes through enough Character Development to start getting over her fear by being familiar with tarts.
• Women Are Wiser: As per the show's enforcement of this trope, she tends to be more levelheaded and on-the-ball than a majority of the male agents she works with.

Agent Otto

Played by: Filip Geljo, Jaden Michael (pilot)

^{Click to see him in the pilot.}

^{Click to see him as an Odd Squad Director.}

A 10-year-old new recruit of Odd Squad. Otto is fascinated by everything that goes on around him and often wants to learn more about the inner workings of his workplace. In spite of his insatiable appetite and his wild eccentricity, he and Olive have a strong bond of friendship and make a perfect team.

• Ascended Fanboy: He's a huge fan of Soundcheck. Not only does he get to meet them on multiple occasions, but he also gets to sing with them.
• Athletically Challenged: In stark contrast to his partner Olive, Otto's skillset does not lie in sports. This is something he willingly points out to Oren in "Switch Your Partner Round and Round" when the agent is looking to insult him, and something that comes up as a plot point in "The O Games" during the eponymous event. About the only athletic thing Otto does well is dribbling a basketball.
• Audience Surrogate: Serves as one for the first few episodes of Season 1, in order to familiarize the audience with both the world of the show and with Odd Squad as an organization.
• Beware the Nice Ones: While he never hits his Rage Breaking Point, he can get close, especially if Olive is in danger.
• Big Eater: Oh yes. You name it, he eats it. And he's got the appetite to match.
• Character Development: He starts to become more serious and experienced as Season 1 progresses, and by "Robert Plant", he becomes confident and skilled enough to tackle oddness solo without Olive's aid.
• Cloudcuckoolander: Of the four main characters, he's definitely the least grounded, but compared to some of the secondary characters he seems quite well adjusted by comparison.
• Desperately Looking for a Purpose in Life: Otto changes his potential future careers on the daily, going from Olympic speed skater to tornado chaser to magician. It doesn't seem to bother him in the slightest.
• Determinator: Oftentimes, he averts this trope, becoming pessimistic and losing hope whenever something odd happens or he hits a snag in a case. However, Olive is usually the one to set him right again.
• Does Not Like Spam: Like Olive, he doesn't enjoy eating Delivery Doug and Delivery Debbie's egg salad pizza combination — he has trouble even trying to fit a bite into his mouth.
• Fake Defector: He pretends to turn to Odd Todd's side in the Season 1 finale, with his first act of oddness being to open all the doors in Headquarters and let creatures run loose. However, he simply plays along to the villain's whims in order to truly defeat him once and for all.
• Grade-School C.E.O.: Becomes this in the Season 1 finale alongside Olive. After the events of The Movie, he goes back to leading his precinct.
• Hidden Depths:
  • "Robert Plant" shows him operating the tubes' main computer just like his partner can, despite having never worked in Maintenance/Transportation.
  • While he loves Soundcheck, a boy band known for their many cheesy love songs, "Mystic Egg Pizza" implies that he loves Silly Love Songs in general, as he grows to like Delivery Doug's song.
  • He is shown to admire hypnotism in "Oscar the Couch", and like Olive, he is easily able to put someone into a trance by following Oscar's instructions of clapping twice and saying "couch alert". However, he has a better grip on the skill than his partner — not only does he learn to clap twice more if he wishes for the hypnotized person to repeat what they said, but he easily masters Olive's method of snapping someone out of a trance despite having never been told it.
  • Numerous episodes show that he's no jock, and is terrible at sports. About the only thing he can do sport-wise is skillfully dribble a basketball. This is in contrast to Olive, who is a Passionate Sports Girl and can play most any sport.
• Huge Guy, Tiny Girl: Otto towers over nearly every single girl in the main cast, including Olive. In the original pilot for the show, the heights are inverted, with him being shorter than Olive.
• Living Legend: From Season 2 onward, he is shown to have the status of being a legendary agent among people, with even the newly-formed Mobile Unit being aware of who he is. Of course, since this is a show full of Medium Awareness and Breaking the Fourth Wall, where some, if not all, characters realize that they're in a TV show, this is to be expected.
• Nice Guy: He is generally nice towards everyone, barring villains.
• Not So Similar: Averted. Odd Todd sees him as a "new Todd" and nothing more than a replacement for him. Otto is quick to retaliate by telling him that he'll never be like him and that he'll be a "regular me".
• Obsessed with Food: Goes hand-in-hand with his Big Eater status. He'll often be distracted by food while on a case.
• The Pig-Pen: While it's more of a subtle trait, a couple episodes have shown that Otto isn't the neatest agent at Precinct 13579. "Trials and Tubulations" shows him eagerly slathering himself in mud at Ms. O's discretion, and "O vs. The Ballcano" reveals that he has a good six years' worth of junk in his locker despite working at Odd Squad for less than a year.
• Platonic Boy/Girl Heroes: With Olive.
• Purely Aesthetic Glasses: He's seen wearing a pair of glasses in "Oscar the Couch", which Orchid (somehow) puts back on his face, but he isn't visually impaired in any manner and doesn't normally wear any kind of glasses.
• Put on a Bus: Leaves with Olive to be a Director for another precinct in the Season 1 finale. Filip Geljo would later go on to star in The Movie before officially departing from the show along with Dalila Bela.
• Rank Up: Is promoted to the Management department and becomes an Odd Squad Director of a neighboring precinct in the Season 1 finale, along with Olive.
• Read the Freaking Manual: He hasn't read his Odd Squad Training Manual due to the fact that he runs on instinct. Immediately after he tells Olive this, he ends up colliding with a door. This is contrasted with Olive, who is presumed to have had read her manual.
• Real Men Wear Pink: In "Rise of the Hydraclops", he grows attached to Oscar's teddy bear, Norman, when the Scientist uses it as a ruler — so attached, in fact, that he's willing to abandon food just to play with the toy and never lets go of it up until he's ordered to take his shoes off by Oscar at the end of the episode.
• Rookie Male, Experienced Female: Otto is new to the Squad while Olive has already had a former partner.
• Savvy Guy, Energetic Girl: Gender Flipped here. Olive is the experienced and calm one to Otto's new and energetic.
• Stalker Shrine: Otto has one in the form of an entire room, dedicated to the four band members of Soundcheck and plastered in everything from shirts to photos to posters. However, instead of being appalled, Danny T is in sheer awe when he is first introduced to it.
• Sitcom Arch-Nemesis: He has an implied bad history with Orchid and often talks to her as though she's a toddler, which isn't helped by her Bratty Half-Pint attitude and The Dreaded status among agents.
• Supreme Chef: While not displayed in-show, the episode "The Confalones" reveals that he makes good meatballs.
• True Companions: With Olive.
• The Watson: As a new recruit, he's usually the one who asks when something needs to be explained.

Agent Oscar

Played by: Sean Michael Kyer

The head scientist of Precinct 13579's lab. Goofy and nerdy, he has a gadget for almost everything. He takes care of his gadgets, and he always greets others with "Hey guys!" He is renowned for creating addable gadgets and for starting the first Odd Squad lab.

• Absent-Minded Professor: Genius, but can be a bit forgetful.
• Beleaguered Assistant: Serves as one to Ms. O in some episodes, often carrying out her orders to fetch her a juice box or make dresses for her. His assistant role is more prominent in the pilot.
• Character Development: Throughout Seasons 1 and 2, he goes from being a timid, awkward scientist who would prefer staying in the lab than going out onto the field to a complete badass who manages to fend off a swarm of hypnotized scientists using the seventeen lab coats he wears. It's topped off by his promotion to President of the Scientists in "Oscar Strikes Back".
• Compressed Vice: "Odd Squad Needs You" shows him being terrified of Ms. O, to the point where he has a bunker set up in his lab for him and Oona to hide in. This is despite the fact that numerous past episodes have shown that, while he is often startled by her actions and frequent yelling, he isn't outright afraid of her.
• Crippling Overspecialization: While he is proficient in building and fixing gadgets, he does not fare well in other positions. This is evidenced by him being fired from over sixty jobs at Precinct 13579, either due to his inexperience or due to his ditzy but timid nature. Because of this flaw, Ms. O creates the Science position just for him so he can put his skills to good use without having to leave Odd Squad.
• Gadgeteer Genius: He makes various gadgets for the Odd Squad agents. Though making gadgets is a thing every scientist does, he's special for the fact he created addable gadgets, a very important tool in Odd Squad. In addition, the Science position as a whole was created for him to put his skills to good use, which spurred other precincts to start their own labs.
• Genius Ditz: He's very smart, but can be a bit awkward.
• Hairstyle Inertia: Averted. Oscar alternates between two hairstyles throughout the show (which is a result of episodes and other side material being filmed at different times), something that "Best Seats in the House" provides an in-universe explanation for. "The Curious Case of Pirate-itis" also reveals that he's gone through six different hairstyles, all of which were copied from Odie, another Scientist.
• Hidden Depths:
  • In "Invasion of the Body Switchers", Oscar becomes stuck in Ms. O's body right before she's set to take her O Test. At one point, he remarks how, if she gets fired, he'll ruin her life. Whether that means he's a heroic Starscream, he's taking advantage of Ms. O's strength, or if he's even being genuine is completely up for interpretation.
  • He is shown to be quite the skilled hypnotist in "Oscar the Couch".
  • "There Might Be Dragons" gives him a chance to show off his electrical skills, managing to restore power to Headquarters despite it taking longer than intended.
• "I Am Great!" Song: "Oscar is Awesome" is Exactly What It Says on the Tin: it's a boastful song about how awesome and badass Oscar is.
• The Klutz: Boy howdy, is he ever.
• Labcoat of Science and Medicine: A trademark of his department.
• Let's Get Dangerous!: Despite his timid, ditzy nature, he's quite proficient in fighting oddness. He even manages to beat Odd Todd — one of the toughest villains of the series — in a 1-on-1 fight using magnets on a handmade vest and a bag full of tomatoes.
• Mad Scientist: While he's not evil, a lot of problems occur due to one of his inventions going wrong.
• Mentor Archetype: He becomes a mentor to Oona in Season 2, teaching her the ins and outs of the Science department before his departure in "Oscar Strikes Back".
• Nerd Glasses: Sports a pair of these that he's often seen adjusting.
• Put on a Bus: Leaves Precinct 13579 to become President of the Scientists at the Odd Squad Academy's Science building in Season 2.
• Rank Up: He is promoted to the position of President of the Scientists in "Oscar Strikes Back", and leaves Precinct 13579 to work in the Science building on the campus of the Odd Squad Academy.
• Real Men Wear Pink: In "Rise of the Hydraclops", he is revealed to have a Security Blanket in the form of a stuffed teddy bear named Norman, which he uses as a ruler to find his way to the secret weapon he has buried.
• Say My Name: It's a Running Gag in Season 1 for someone to scream his name, usually in a frustrated manner and usually when he gets off-track.
• Selfie Fiend: In "Picture Day", he not only treats photography as Serious Business, he spends at least nine hours taking selfies of himself and completely forgets about going out to eat with Olive and Otto.
• Smart People Build Robots: He builds 25 Oscarbots that look nearly identical to him in order to build Ms. O the perfect juice box. They look and act so humanoid that Olive has to ask in sheer disbelief if he cloned himself upon watching them all gather together in the bullpen.
• Teen Genius: See Gadgeteer Genius.
  • A sidenote: he ages further in the Season 2 premiere, due to his actor aging in real time. In-universe, this is due to an aging gadget going off.
  Ms. O: Something's different about you.
  Oscar: Oh yeah. This Make-You-Older-inator went off. I like the new voice, though.
• Textile Work Is Feminine: Inverted — Oscar is shown to be quite the capable tailor, and can make quite a lot of clothing in a short span of time.

Season Two

Agent Olympia

Played by: Anna Cathcart

Otto's replacement and one of the main characters of the second season.

• Bespectacled Cutie: Olympia's cute and a glasses wearer.
• Beware the Nice Ones: Sure, Olympia's a Genki Girl, but she's not afraid to show her mean side.
• Character Blog: Olympia hosted the first season of OddTube, a 20-episode vlog. She passes the torch to Orla for the second season.
• Contrasting Sequel Main Character: While only a new cast for a new season, this still applies as Otis and Olympia have the exact opposite dynamic as Olive and Otto, save for Olympia being the one who's the protocol fiend and the chipper bouncy one while the more reserved Otis is frequently sighing in irritation at her antics.
• Crippling Overspecialization: Olympia may be hard-working and skilled while solving cases as an Investigation agent, but put her in the Maintenance position and she becomes very overwhelmed very quickly.
• Cute, but Cacophonic: When she screams or shouts, whether scared or excited, it is incredibly loud.
• Dreadful Musician: Averted. Not only does she have strong vocals, but can also play instruments such as a ukulele and a keyboard.
• Genki Girl: Olympia is very enthusiastic and full of energy.
• Fangirl: Olympia's one of Otto and Olive, and freaks out every time she gets to meet them.
• Fatal Flaw: Her lack of belief in villains making Heel-Face Turns. It bites her in the butt big time in the Season 2 finale upon finding out that Otis was a former villain, as he and Ms. O get fired from Odd Squad as a result.
  • By far her biggest flaw is her obsession with work. She will often overwork herself with the overall goal of being the best agent Odd Squad as an organization has ever seen, as well as wanting to impress others such as Olive and Ms. O, refusing to relax or take a vacation until Ms. O herself forces her to as per an existing rule — to such an extent that once she gets going, she becomes physically unable to stop herself. However, her Workaholic tendencies often get in the way of anything not involving work, such as having lunch with Otis.
  • Her other big flaw is her drive for perfectionism, which goes hand-in-hand with her aforementioned Workaholic flaw. Even for something as casual as a party for a departing co-worker, she strives for perfection in nearly everything she does, and if someone tells her that she's not perfect at something she does, she will go to incredible lengths to hunt them down and confront them with nary another thought. Her desire to be a perfect agent has caused trouble for her co-workers on more than one occasion, especially Otis, who often reminds her that she doesn't need to be perfect and that failing at something is normal and acceptable to do.
  • She is physically unable to say "no", which causes her issues in "Olympia's Day" when Ms. O opens up a room for her and the Noisemaker to talk things out in. Dr. O and Ocean both catch on to the opening and ask Olympia to stay in the room, and it gets progressively worse from there as more agents get wind of the new room due to Olympia accidentally letting it slip. It gets to a point where, after cramming 16 agents into the room, she goes through massive Sanity Slippage and ends up hallucinating before passing out (an occurrence known as "slipping into mathness").
• Foil: To Ohlm. Both of them were excellent students at the Odd Squad Academy. But while Olympia was happy to just be an agent, Ohlm wanted to become the Big O immediately. This resulted in him plotting to take over Odd Squad.
• Hidden Depths: If the Cold Open of "License to Science" is any indication, Olympia knows how to play football pretty well and can hold her own against three football players dressed in uniform.
  • "There's No O in O-bot" reveals that she's taking piano lessons, and is skilled enough to be able to read sheet music.
  • In "New Jacket Required", she's able to tell that Otis is wearing a new jacket by noting tiny details such as stitches and lapel size.
• The Knights Who Say "Squee!": She is a big fan of Olive and Otto as well as their work, and idolizes them to incredible degrees. When she meets them in-person for the first time in The Movie, she becomes so starstruck that she can't form a coherent sentence.
  • She also idolizes Orla, albeit to a far lesser extent, complimenting her on her Spock Speak and her many adventures with the Mobile Unit.
• Motor Mouth: She talks a lot, and isn't afraid to weaponize it if need be.
• Nice Girl: She's very sweet and kind.
• The Perfectionist: Holy moly, is she ever.
• Reformed, but Rejected: Her Fatal Flaw. She believes in "once a villain, always a villain", and doesn't think that villains that have genuinely reformed can change for the better. She gets better by the end of Season 2.
• Savvy Guy, Energetic Girl: Olympia is a Genki Girl while Otis is more reserved.
• Platonic Boy/Girl Heroes: With Otis.
• Plucky Girl: Like her predecessor, Olive, Olympia tries hard and is a diligent agent.
• True Companions: Best friends with Otis.
• Workaholic: And how.

Agent Otis

Played by Isaac Kragten

Olive's replacement and one of the main characters of the second season. He came from... somewhere. Like Olympia, he is introduced in the second season premiere.

• Absurd Phobia: Otis is not a fan of ducks. He thinks it's his old family coming for him.
• All-Loving Hero: He's a friendly agent in the Squad and he always sees the good in people no matter how evil they are.
• The Cast Showoff: Kragten is a professional dancer, and Otis is shown dancing more than once in the series.
• Crippling Overspecialization: Like Olympia, he is skilled on the field, but can't handle the consistent workflow that the Maintenance position in particular has.
• Dark Secret: He used to be a villain.
• Flight: Is revealed to be able to fly in the Season 2 finale.
• Heel–Face Turn: Is revealed to be the White Sheep of a villainous duck family.
• Hidden Depths: Season 2 reveals quite a few hidden things about Otis.
  • "A Job Well Undone" implies that Otis has a talent for face-painting, as he draws a cat on Hopkins' face at the birthday party.
  • In the Cold Open of "Rookie Night", he delivers some kind words to a plant with an attitude issue and acts very much in the vein of a therapist for it. Later on, he reveals that he automatically denies any chance to try new experiences, doing so when offered to go skydiving for the eponymous event before changing his tune when he learns what skydiving is.
  • The ending of "Sir" reveals that Otis is a good chef, in contrast to those like Olympia, who can't even bake a cake by following a recipe.
  • Another contrast Otis has with Olympia is his hidden disdain for talent shows, as revealed in "Agent Orchid's Almost Half-Hour Talent Show".
  • In "The Ninja Situation", Otis shows off just how skilled he is in battle. His agility allows him to dodge most of the Evil Ninja's attacks.
  • Like Olympia, Otis also displays some skill in playing football in the Cold Open of "License to Science".
  • "There's No O in O-Bot" reveals that Otis is taking yoga classes at a hot yoga studio in town.
  • He enjoys eating oranges, and gets some as part of Joy LaFleur's deluxe track-and-field package in "Where There's a Wolf, There's a Way". In addition, "Back to the Past" reveals that he also loves hot dogs, and "Slow Day" reveals that he hates pickles, thinking of them as a "wet vegetable".
  • "Odd Squad Needs You" reveals that while Otis loves movies, he's not so skilled at making them.
  • In "Who is Agent Otis?", he demonstrates a knack for sewing, as he is shown putting together a blanket made out of duck feathers. He also may have a little Scientist blood in him, considering he built a translator voicebox for his duck family to use.
  • Just as Olympia is able to play a keyboard in "Show Me the Money", Otis is also able to play a saxophone.
  • While it's justified as Isaac Kragten is a professional dancer, "The Creature Whisperer" features Otis' dancing ability for the first time, as he does so in order to stall the presumed Big O.
  • A brief conversation with Olympia in "And Then They Were Puppies" reveals that Otis is Not a Morning Person, and while he can wake up easily, he often goes back to sleep once he does. There's some Fridge Brilliance to be found here — ducks often employ power naps to get sleep and sometimes sleep in rows (those at the end of rows are light sleepers). Since Otis is a human raised by ducks, this would explain his abnormal sleep habits.
  • In the OddTube episode "Otis Fills In", he dances to a Soundcheck song while the camera is still running, which implies that he may like the band and/or their music.
• Mysterious Past: Like in Oscar's words, "Then where did he (Otis) come from?" Otis's past is the main mystery of the second season. It is hinted to have something to do with villains and is confirmed.
• Raised by Wolves: He was raised by ducks.
• Read the Freaking Manual: Otis has not read the Odd Squad handbook at all. This is contrasted with Olympia, who loves to get her hands on anything OS related.
• Savvy Guy, Energetic Girl: As noted above, he is the Savvy Guy to Olympia's Energetic Girl.
• Socially Awkward Hero: When he started off, Otis wasn't very good at communicating with others. He got better.
• Supreme Chef: The end of "Sir" reveals that he is apparently quite the skilled cook.
• Undying Loyalty: To Ms. O, after she helped him put an end to his duck family's Evil Plan and trained him herself to be an agent of Odd Squad.
• Walking Spoiler: It's hard to talk about him without exposing his past.
• White Sheep: Of his family of ducks. He didn't want to destroy the world, and subsequently left to join Odd Squad.

Agent Oona

Played by: Olivia Presti

Oscar's assistant and eventual replacement, becoming the head of the Science Department.

• Absent-Minded Professor: Also quite smart, but occasionally forgets things and trails off.
• The Apprentice: She serves as Oscar's assistant in Season 2 until "Oscar Strikes Back", where she takes over his position as Lab Director of Precinct 13579.
• Beware the Nice Ones: Let's just say that pissing someone who's Cute and Psycho off is a very bad idea.
• Big Damn Heroes: Saves the day in spectacular fashion in "Oscar Strikes Back."
• Cute and Psycho: Oona is a Gadgeteer Genius who is nice to her co-workers and is loyal to Odd Squad through thick and thin. However, unlike her predecessor and mentor, Oscar, her mental health isn't in the best state, and she is often shown to be completely wacky and insane. Perhaps the best example of this is in the episode "The Cherry-on-Top-inator", where she becomes giddy from destroying useless gadgets with her trusty mallet, coupled with murderous screams.
• First Day from Hell: Her first day on the job has her accidentally sending herself, Oscar, Olympia and Otis back in time and working together with them to prevent a timetastrophe.
• Gadgeteer Genius: She is a scientist, hence this is her job.
• Genius Ditz
• Labcoat of Science and Medicine: A trademark of her department.
• Mad Scientist: A bit nuts. She tends to go off a bit, like her calculator outburst in the movie or her gradual Sanity Slippage in "Cherry-On-Top-Inator."

Other Agents

Agents Oren and Olaf

Oren (left) and Olaf (right)

Played by: Brendan Heard (Oren) and Eshaan Buadwal (Olaf)

Two recurring supporting characters. They are often opponents of Otto and Olive.

• Absurd Phobia: Oren seems to be scared of pancakes.
• Blatant Lies: During a "Meet the Agents" sequence, Oren says that he's great at sharing (followed by a clip of him and Olaf fighting Olive and Otto over new office chairs) and that's he's a very hard worker (followed by a clip of him and Olaf lounging in the ball pit).
• Catchphrase: For Olaf: "I'm Olaf!"
• Cloudcuckoolander: Olaf is possibly the most odd-ball member of Odd Squad, which is saying something.
• Hidden Depths: Olaf tends to be simple-minded, but can have surprising moments of genius. For example, in one episode, Otto keeps shrinking and Olive has to team up with Oren and Olaf to find a cure. Olaf proves to be the only one who knows the secret to reversing the shrinking, and his normally very limited vocabulary begins to approach Sesquipedalian Loquaciousness.
• It's All About Me: Oren.
• Kindhearted Simpleton: Olaf may not be all that bright, but he's extremely friendly and cheerful, in stark contrast to his jerk-ish partner.
• Noodle Incident: "If Ms. O offers to send you to Blobsylvania to count blobs, DO. NOT. GO." Subverted in that we get to see a clip of Oren and Olaf counting blobs.^note It's from the end of the Blob on the Job episode.
• Perpetual Smiler: Olaf is almost always happy and excited, which sometimes gets on Oren's nerves.
• The Reveal: Olaf is a werewolf
• Sitcom Arch-Nemesis: To Olive and Otto.
• Those Two Guys: Agents who appear every so often to annoy our heroes.
• Trademark Favorite Food: Olaf loves potatoes.
• True Companions: Really do care for each other.

Agent Orchid

Played by: Michela Luci

One of the younger agents, she is sassy and particular.

• Character Development: Season 3 had her go from being The Dreaded agent with an attitude problem to an agent who, while still viewed in a negative light by others, is more tolerant of others' actions.
• Cute and Psycho: Orchid is to be feared.
• The Dreaded: Just hearing they have to deal with her can make Otis groan.
• Little Miss Snarker: Always has something vaguely rude/insulting to say.
• Sitcom Arch-Nemesis: She and Otis aren't fond of each other. Neither are her and Otto, as they share an implied bad history.

Agents Octavia and Oz

Played by: Julia Lalonde (Octavia) and Carson Reaume (Oz)

Octavia, another agent, will appear here and there in Season One. She is not the smartest tool in the shed, but always tries to be helpful. Her partner, Oz, is only seen in flashbacks, and for good reason.

• The Ditz: Agent Octavia. She doesn't always understand things.
• Invisibility: Agent Oz, thanks to looking at a gadget the wrong way.
• Nice Girl: Octavia is there to help, even if she doesn't know what's she's doing.

Agent Ohlm

Played by: Jaiden Cannatelli

Introduced in the first season finale. Quite dimwitted.

---

• Bond Villain Stupidity: Ohlm was so focused on getting revenge on Odd Squad that he didn't stop to think about himself getting sucked into his own black hole. He could have used a getaway vehicle or something to escape his own doom.
• Crouching Moron, Hidden Badass: While looking and acting dumb, he is still a good agent and succeeds in getting the remote for the Puppy Ray back.
• Evil All Along: Revealed to have been plotting to take down Odd Squad since he started working here, because he wasn't made the Big O immediately upon graduating the Academy.
• Foil: To Olympia. Both of them were excellent students at the Odd Squad Academy. But while Olympia was happy to just be an agent, Ohlm wanted to become the Big O immediately. This resulted in him plotting to take over Odd Squad.
• Four Eyes, Zero Soul: When Ohlm reveals his true colors in the Season 2 finale, he puts on a pair of glasses.
• Knight of Cerebus: Hey you know all those Affably Evil villains on the show who are rather good friends with the Squad? Well you're not going to find any of those traits in this child.
• Last Episode, New Character: Season 1 ends with Ohlm being introduced as Otto's temporary new partner, and continues to appear throughout Season 2 as a recurring character.
• Obfuscating Stupidity: He used his dumbness to hide his real plans to destroy Odd Squad.
• Repetitive Name: His full name is Ohlm Ohlm.
• Ungrateful Bastard: You'd think that Ohlm would have been grateful that the agents were willing to save his life after they found out his true colors, but no, he continues threatening to destroy the company after they closed his black hole and doesn't even thank them. Yeah, he had that grounding coming.
• Walking Spoiler: He's been faking his ditziness to help villains to sabotage his precinct, so he could manipulate events to get Ms. O fired and destroy Odd Squad.
• You Are Grounded!: Is grounded by his parents when defeated by Ms. O.

Agent Obfusco

Played by: Jaeden Noel

He's an expert on dealing with oddities and trains current agents. However, he talks in a weird way, which means it's hard for agents to understand him.

• The Dreaded: All you have to do is mention his name, and the agents will scream in his presence.
• Hypocritical Humor: He complains nobody can understand his sister.
• Meaningful Name: Obfuscate, meaning to "render [something] unintelligible" or to "bewilder".
• Stealth Pun: Agent Obfusco has a plant named... Robert.
• Talkative Loon: Agent Obfusco speaks almost exclusively in Meaningless Meaningful Words, Insane Troll Logic, Word Salad Philosophy, and Sesquipedalian Loquaciousness. Without his mustache, he talks normally.

Dr. O

Played by: Peyton Kennedy

Obviously, the Doctor of Precinct 13579.

• Always Introduces Themselves: A standard conversation with her will often start with “Hello I’m Dr. O, we work together at Odd Squad” “Yes I know who you are”. She has done this even to people she was talking to shortly before or should know well (like when she reminds Oscar of the time they went on a mission together).
• Bizarre Taste in Food: Her favourite food is apparently unicorn tears.
• Catchphrase:
  • "Trust me, I'm a doctor".
  • Also "WHAT'S NEXT??".
  • "I'm a doctor, not a (whatever)"
• Child Prodigy: While all agents of Odd Squad can count as this to various extents, Dr. O is a notable example due to her claim of having gone through eight years of medical school to become a doctor. While how and where she did this is not shown, the fact that The Movie shows her working in what appears to be a real hospital after Odd Squad is shut down indicates her qualifications are not only real but are also recognized by adults.
• The Comically Serious: She is less prone to acting silly, and gets down to business. Her abrupt deadpan and straight face contrast with everyone else's behavior, making her funny.
• I'm a Doctor, Not a Placeholder: Dr. O is always reminding everyone that she's a doctor.
• Lab Coat Of Science And Medicine: Wears a labcoat over her Odd Squad medical uniform. Unlike the white labcoats of the scientists, hers is a light blue. Also, while all scientists are shown wearing their own labcoats, minor and background medical staff do not, suggesting the labcoat is specifically part of her position as the head Odd Squad doctor.
• The Medic: Is the main Doctor of Precinct 13579 before being Put on a Bus in Season 2 (see below).
• Put on a Bus: Departs for the Odd Squad Space Station in "Doctor O, Party Time, Excellent."
• Super Doc: The only one at Precinct 13579, and knows how to treat both oddities and normal illnesses.
  • In a bit of a subversion, it's implied that she is NOT a good doctor, considering she always tells her patients "I tried my best.", according to her.
• Trust Me, I'm an X: She says stuff like this often.

Agent Oksana

Played by: Madeleine Barbeau

The cook of the precinct. Is neither talkative nor emotional.

• Absurdly Dedicated Worker: In The Movie, Odd Squad is shut down. However, Oscar and Ms. O discover that's she's still cooking and making food there.
• The Comically Serious: Even more than Dr. O: her Emotionless Girl tendencies mixed with her sarcasm make her hilarious to viewers, though scary to her teammates.
• Crazy-Prepared: Always keeps pudding on hand in case of a invisible dinosaur invasion. It was even in her video guide.
• Creepy Monotone: Speaks in one.
• Deadpan Snarker: Many of her lines are sarcastic, and she's actually deadpan.
• Emotionless Girl: You'll get no reaction from her.
• Jerk with a Heart of Gold: Makes unreasonable demands in "Agent Oksana's Kitchen Nightmares" (like multiple bars of gold), but it's eventually revealed that she needs the items to get the best food for the squad.
• Team Chef: Until the events of "Dr. O No", she is the sole cook of #13579. Whether she is a Supreme Chef or Cordon Bleugh Chef is unknown, though evidence points to the former.

Ocean

Played by: Elijah Sandiford

A new employee, he works with odd creatures. He's an expert at dealing with them and taking care of them.

• Fluffy Tamer: His expertise extends to frightening animals, and cares for them as well.
• Friend to All Living Things: He is very fond of creatures and will risk his life to give one the chance of survival.
• Mellow Fellow: So laid-back it's amazing he doesn't slide out of his hammock onto the floor.
• Nature Lover: Comes with his love of animals.
• The Watson: Ends up having to ask the questions, such as in "A Case of the Sillies" where he needs to know about measurement quantities.

O'Donahue

Played by: Tate Yap

Oprah's former partner who worked at Odd Squad until the 1980s, when he quit due to failure in solving a case. As of "Happy Halfiversary", he is unretired and works as an undercover Investigation agent for Oprah.

• The Charmer: In "Totally Odd Squad", it's shown that he has no issue flirting with his boss. Unfortunately, any romantic feelings he has for her is completely one-sided on his end.
• invoked Disabled Character, Disabled Actor: Played with. Tate Yap wears a hearing aid in real life, but it's never revealed whether O'Donahue has any sort of hearing impairment.
• Enemy Mime: Becomes one as part of The Infiltration seen in "Behind Enemy Mimes".
• First-Name Basis: He is one of the few who is allowed to call Oprah by just that: Oprah, instead of her job title, "Ms. O". This is due to the fact that they were partners, and so she has no issue with him referring to her as Oprah.
• Hawaiian-Shirted Tourist: He often is shown wearing a blue Hawaiian shirt under his navy jacket instead of the white button-down undershirt most Investigation agents wear, and also donned a red one in "Behind Enemy Mimes". He also wears a Hawaiian shirt as a fisherman.
• Heroes Gone Fishing: He became a fisherman after retiring from Odd Squad, and remained as one for thirty years until Oprah begged for his help solving a cold case and he had a He's Back! moment.
• Horrible Housing: Odd Squad: World Turned Odd shows that O'Donahue's house is situated in a deep part of the woods, with only a table with three chairs and a bench as furniture. It's not made clear if this is his place of residence in the show, however.
• Mandatory Unretirement: He willingly came out of retirement in "The One That Got Away" when Oprah went to him for help in catching a villain who was stealing half of everything. By the end of the episode, it's implied that he went back into retirement right after solving one more case revolving around shoes being stolen from people, but "Happy Halfiversary" shows that he is back working for Odd Squad as an Investigation agent, having been attempting to make peace with the Queen of the Ice Trolls for five years, while "Behind Enemy Mimes" reveals that he is secretly working undercover for Oprah performing an infiltration of a villain trio known as the Thrimes.
• Named After Somebody Famous: He's named after Phil Donahue, someone who directly influenced Oprah Winfrey — fitting, considering he's Oprah's former partner and almost always has her back.
• That One Case: He quit Odd Squad due to failing to solve a case regarding a villain stealing half of various things, leaving his symbol behind as parting gifts. Thirty years later, in "The One That Got Away", he revisits the case with Oprah after she asks for his assistance, and the two manage catch Equal Evan, the villain in question.
• Time-Passage Beard: Subverted. When Oprah comes across him in "The One That Got Away", he's shown with a full beard. However, it's revealed that the beard is fake when he rips it off while doing a Spy-Tux Reveal.
• Totally Radical: Spoke in a combination of this and Valley Girl often back in the 1980's. He takes it down a notch in modern times.
• True Companions: With Oprah. Even long after he quits, the two remain close.
• Undying Loyalty: Odd Squad: World Turned Odd reveals that even in a crapsack Villain World, O'Donahue will absolutely refuse to turn to the odd side because "I do no odd."
• Vocal Evolution: His voice gets noticeably deeper beginning in Season 2.

New Dr. O / Olly

Played by: Sasha Steiner

Dr. O's initial replacement before being transferred to the Food and Beverage department and becoming Oksana's replacement.

• Accidental Misnaming: She has a tendency to mispronounce Oona's name often.
• Best Friend: In "Dr. O No", Oona becomes New Dr. O's go-to person if she needs help with her Odd Squad Doctor duties, and she quickly becomes friends with her. However, the friendship is completely one-sided on New Dr. O's end, as she fails to realize just how much her antics are stressing Oona out.
• Big Brother Is Watching: She's convinced that Precinct 13579's cafeteria workers are constantly watching people and are evil to boot.
• Cloudcuckoolander: By God, is this girl eccentric — to the point where she even manages to unnerve Oona, who is a Genius Ditz herself. She's arguably one of the zaniest characters seen on the show, and that's saying something.
• Comically Inept Healing: In "Dr. O No", it's clear that she has no idea how to cure odd illnesses, and even with Oona helping her out she's still incompetent. Unsurprisingly, she is transferred to the Food and Beverage department at the end of the episode.
• Innocently Insensitive: Her debut episode, "Dr. O No", has her be completely oblivious to Oona's needs and feelings, which causes the Scientist to grow increasingly frustrated and stressed to the point where Ms. O, asking about a patient with tentacle feet, manages to make her hit her Rage Breaking Point.
• Labcoat of Science and Medicine: She wears one of these while working in the Medical department.
• Leader Wannabe: In "Hands on a Desk Chair", she attempts to join in on the competition to see who gets to be Precinct 13579's Director for a day, only for Olympia, Ocean and Orchid to protest. She doesn't get far before Orchid effectively scares her into changing her mind.
• Meaningful Rename: Following the events of "Dr. O No", she is referred to as "Olly", which signifies her not being a part of the Medical department anymore (and no longer filling the role of being the former Dr. O's replacement). It's also an O name like what all other agents of Odd Squad have.
• Offscreen Teleportation: New Dr. O manages to not only swap out Oona's white undershirt for an "anti-caf" shirt within seconds, but she also manages to somehow slip a flatbread sandwich into her pocket, without touching her once.
• Stealth Hi/Bye: She has the ability to do this, which is best demonstrated in "Dr. O No" when she manages to pop up next to Oona, who is all the way in Yellowstone National Park.
• Supreme Chef: Like Oksana before her, New Dr. O is a very skilled chef.
• Who Names Their Kid "Dude"?: "New Dr. O" is revealed to be the name that she was born with, and because of it, Ms. O promotes her to be Dr. O's replacement. However, it's soon revealed that "New Dr. O" isn't as skilled at being in the Medical field as previously thought, and as a result, Ms. O moves her to the Food and Beverage department. She is renamed "Olly" in "Haunt Squad" and is referred to as such from that episode onwards.
• You Are What You Hate: She shows complete disdain for Odd Squad cafeteria workers for no apparent reason, and tries to get Oona to hate them as well. By the end of "Dr. O No", she's transferred to the Food and Beverage department and becomes a cafeteria worker herself.

Xavier and Xena

Played by: Leonidas Castrounis (Xavier) and Sheena Darnley (Xena)

A partner pair from the Task Force department who are sent by the Big O to monitor Precinct 13579 in Season 2.

• Affection-Hating Kid: They hate hugging and kissing. Xavier in particular also hates handshakes.
• Bullying the Disabled: Xavier is more than willing to take Olympia's glasses with him when he and Xena begin marking things from Precinct 13579 that they wish to take with them when it gets shut down. Since Anna Cathcart does wear glasses in real life, if Xavier took Olympia's glasses, she'd potentially be Blind Without 'Em.
• Disability as an Excuse for Jerkassery: Xena is disabled and uses a wheelchair to get around. While she doesn't use her disability to excuse her actions, her being in a wheelchair, Odd Squad's modus operandi of equality (as well as the overall show's theme of diversity), and her high status in the organization's hierarchy are potential reasons why agents don't confront her for what she's done.
• The Dividual: They are never seen apart and always work together as a partner pair.
• Everyone Has Standards: They may be more than willing to mistreat other agents and take their workplace away from them, but when it comes to firing Orson in "Saving Agent Orson", seeing that he has superpowers like sizeshifting and flight is enough to scare them into admitting defeat and letting him stay.
• Evil Counterpart: Both agents serve as these to Owen and the rest of the Security department. Not only is the Task Force department logo an evil version of Security's (with the keyhole flipped upside down and being colored black), but while Xavier and Xena are selfish and greedy and have little regard for others' well-being, Owen and the other Security agents are laid-back and are generally affable. In addition, Owen in particular can be unhelpful, but doesn't have any malicious intent behind his actions.
• Gender Flip: Xena was originally referred to as male in casting call scripts, while Xavier was of an Ambiguous Gender. In the series proper, Xena is female and Xavier is male.
• Gold-Colored Superiority: They both wear gold as part of their outfits, and have a lot of gold-colored objects in their office.
• Hate Sink: Both of them effectively serve as these, what with their mistreatment of Precinct 13579's agents, their selfishness, and their actions being more villainous than heroic — not to mention they are both Karma Houdinis by the season's end.
• Hypercompetent Sidekick: Both of them work directly under the Big O, who is a Clueless Boss. Despite the fact that he doesn't seem to know them, however (shown in "Who is Agent Otis?" when he refers to them as "you other guys"), they are more than happy to carry out his orders. As of Season 3, it's unclear if they fulfill this role to Oprah, who becomes the new Big O.
• Karma Houdini: Neither one of them get any sort of comeuppance for their misdeeds, and their final appearance in Season 2 is them departing from Precinct 13579 following the Big O firing Oprah and Otis from Odd Squad.
• Lack of Empathy: Even when agents' physical and mental health are suffering, they show absolutely no empathy...that is, for anyone but themselves.
• Letter Motif: Xavier and Xena, like others in the Task Force department, are referred to as "the X's". They also wear X-shaped buttons on their jackets, and Xena wears bobby pins in her hair that form an X shape.
• Meaningful Rename: Xavier and Xena were initially named "Oke" ^note A South African term used to address a boy and "Opaganda" in casting call scripts, respectively, before being renamed. While casting calls for "Oke" were looking for an actor who was African-Canadian to play the character, "Opaganda" was originally meant to be the personification of propaganda — something that would have been a bit too mature of a subject matter for PBS Kids to allow.
• Mirthless Laughter: They often laugh in a stiff, awkward, unisonant manner. Doubles as an Evil Laugh.
• Rules Lawyer: Their job, and by extension their department's job, is to make sure that Odd Squad precincts are following rules. If they find that a precinct is not following rules, they have the power to shut them down permanently.
• Screw the Rules, I Make Them!: In "Xs and Os", they have no problem with accusing Precinct 13579 of being over budget while also buying expensive things for themselves. Them doing so turns out to be the cause of the precinct's financial woes.
• Seven Deadly Sins: Both Xavier and Xena have Greed, Pride and Wrath as their character-defining traits.

O'Beth

Played by: Lisa Pryce

One of the two agents of the IT department at Precinct 13579, the other being O'Seth, her cousin.

• All Girls Like Ponies: She likes unicorns.
• Clashing Cousins: Averted. She and O'Seth have a good relationship and hardly argue with each other.

Odie

Played by: Percy Hines White

The Lab Director of the precinct in the next town over from Toronto (wherever that is).

• Brainwashed and Crazy: "Oscar Strikes Back" sees him as one of the many Scientists under the megalomaniac Obbs's mind control, and he antagonizes Oscar far worse than he did in "The Curious Case of Pirate-itis".
• Excellent Judge of Character: When Oscar comments on how Obbs is showy, Odie takes one look at his entrance and determines that he is, indeed, a little showy. This is only a minute before he gets put under mind control by Obbs.
• Gadgeteer Genius: Like Oscar, his stock-in-trade is gadgetry, and he's shown to well know his way around a gadget.
• Hair of Gold, Heart of Gold: His hair is blonde, and he is firmly on the heroes' side.
• Literal-Minded: As part of his stupidity under Obbs's mind control, he takes his master's commands pretty literally. Telling him to take an entire box of tissues to clean himself will result in him using the box itself as a cleaning tool rather than a bunch of tissues.
• Plagiarism in Fiction: Odie has a raging hatred for Oscar because he stole his haircut designs, which is, of course, treated as absolute Serious Business by both Olive and Otto. Once he realizes that Oscar stole his haircut designs out of jealousy and respect and not out of any malicious intent, they make up and become friends again, and Odie eventually gets an original hairstyle (though not without Oscar becoming jealous over it).

Olo

An agent who works as the head of the Glue department (as well as its assistant deputy commissioner, maybe) at Precinct 13579.

• Barrier Maiden: Her frequent gluing of things in Headquarters causes its existence, prevents its collapse, and ultimately prevents its destruction. When she is forced to cut back on supplies, items ranging from support beams to bricks begin falling and desks begin to crumble. To top things off, the glue she uses is school glue and not anything heavy-duty.
• Duct Tape for Everything: Olo is the head of the Glue department, and specializes in keeping Headquarters sturdy by gluing pieces together with school glue.
• Fictional Greetings and Farewells: She greets people by using her name as a pun on "hello".
• Gravity Master: In the OddTube episode "Meet Agent Olo", she has the ability to move any chair she's sitting on by scrunching her body up tightly into a ball and saying "meeeeeep", without using any sort of outside forces to move it. According to her, it's something carried over from when she was a dust ball, as she would use that method to move.
• Reduced to Dust: "Meet Agent Olo" has her telling the story of when she accidentally turned herself into a dust ball by accidentally knocking over the Dust-Ball-inator gadget. She couldn't speak, nor could she move very far, only being able to move by curling into a tight ball and saying "meeeeeep". She remained as a dust ball for nearly a month until she landed on the gadget and a passing Scientist kicked the activation button with his foot, causing her to turn back to normal. Not a few minutes later, she scored an interview with Olympia on OddTube.
• Sound-Effect Bleep: The "meeeeeep" noise she makes has shades of this, though there's no swearing in any part of the franchise. Eventually it fell into Memetic Mutation territory among the fandom, and some began to use it in place of swear words.

Ori

^{Click to see him as an Odd Squad agent.}

Played by: Samuel Faraci

A young agent-in-training who eventually becomes an Investigation agent at Precinct 13579.

• Character Development: In "Hold the Door", he was a kid who made Olive and Otto Badly Battered Babysitters by disobeying them and running away from them, being constantly curious and inexperienced. By "Worst First Day Ever", he has matured into a more well-adjusted agent who largely knows how to handle his own.
• Curious as a Monkey: In his debut episode. Ori presses buttons on gadgets he fiddles with, goes inside rooms that are deemed too dangerous for even experienced Odd Squad agents to go into unless they know what they're doing, and mingles with creatures who want to kill him. He mostly grows out of this by "Worst First Day Ever", where he experiences his first day as an Investigation agent, but is still curious enough to open up the Centigurp container, which allows him to keep his job and escape being fired.
• Mike Nelson, Destroyer of Worlds: At the end of "Worst First Day Ever", he manages to cause a timetastrophe by pressing a blue button in the Lab, causing everyone to flee Headquarters and showing that while he may have matured, his curiosity hasn't really gone away in full.
• Offscreen Teleportation: Some characters have a tendency to do this to a certain degree if they're not engaging in Stealth Hi/Bye, but Ori takes it to an entirely new level. As one example, he manages to retrieve a sizeable gadget from Otto's pocket without him noticing, even though it's agents' backs that are treated as Hammerspace.
• Rank Up: The end of "Hold the Door" has Oprah giving him a badge and making him a full Investigation agent, although he runs away before he can take the badge and leads everyone to begin chasing after him again. "Worst First Day Ever" shows that he did still manage to get promoted regardless.

"O"/The Big O

Played by: Christian Corrao

The leader of Odd Squad throughout Season 1 and Season 2 prior to Oprah being promoted in his place.

• Actually, That's My Assistant: In "The Creature Whisperer", he tests Oprah by sending a much older decoy agent in his place, donning the same uniform and calling himself the real Big O.
• Everyone Calls Him "Barkeep": He is only referred to as "[the] Big O".
• Grade-School C.E.O.: Second only to Orson in being one of the youngest authority figures of the show. While it's never revealed whether he is long-living or not, he is at least physically old enough to be able to attend kindergarten.
• Judge, Jury, and Executioner: Barring the executioner, the Big O fills the roles of both the judge and the jury in "Who is Agent Otis?".
• The Leader: Of Odd Squad as an organization.
• Lethally Stupid: Odd Squad: The Movie has him putting every single one of his employees out of a job because he thinks fighting Weird Team is a losing battle. This is in spite of Odd Squad having determination and perseverance as some of its modus operandis.
• Kangaroo Court: Otis's trial in "Who is Agent Otis?" is full of bias and contradictions, which isn't helped by the fact that the Big O is only the judge because he likes to play dress-up.
• Kneel Before Frodo: Proper protocol for his arrival includes getting down on one knee and assuming a pose similar to that of the Thinking Pose.
• Kubrick Stare: He does a rather menacing one when he first reveals himself.
• Pointy-Haired Boss: Due to being so young, the Big O is very naive, which can lead to him making rather idiotic decisions. Odd Squad: The Movie has him throw in the towel against Weird Team instead of trying to fight back, while "Who is Agent Otis?" has him find Otis and Oprah guilty of trying to destroy Odd Squad on weak and biased evidence and has him forget Olympia's and the X's names entirely. "Odds and Ends" even has him promote Ohlm in Oprah's place because he gave him an action figure, which is a decision that doesn't sit well with anyone.
• One-Letter Name: His badge number is 15, meaning his name is simply "O".
• Remember the New Guy?: The existence of a "Big O" wasn't so much as alluded to in Season 1 (though the Big Office was mentioned once). In Season 2, he's treated as though he's been the head of Odd Squad the entire time.
• Villain in a White Suit: Inverted. He wears predominantly white, but he's not so much villainous as he is naive.

One-Shot Agents

O'Seth

Played by: Anton Gillis-Adelman

One of the two agents of the IT department at Precinct 13579, the other being O'Beth, his cousin.

• Clashing Cousins: Averted. He and O'Beth hardly ever get into an argument and are on good grounds with each other.

October

Played by: Kiara Groulx

An Investigation agent who only works during the month of October.

• Meaningful Name: Her name is October, and she only works in October.
• Rules Lawyer: If her stopping her co-workers from carrying heads of lettuce in Headquarters due to a rule that prohibits such is any indication.
• Ultimate Job Security: For working only a single month out of the year, it's impressive how she's able to keep her job.
• You Shall Not Pass!: Her one and only appearance involves her stopping Olympia, Orchid and Ocean from proceeding with the heads of lettuce they're carrying because they're breaking a rule, only for them to remind her that it's not October, and thus should not be working. After that, she lets them pass.

O'Fur

Six kittens who are all agents of Odd Squad. Four of them serve as Oprah's skilled code-breakers, and all of them share the same name.

• Cats Are Superior: Played with. None of them think they're superior than other animal species both odd and normal, but they are all referred to as "genius kittens" by Olympia who are incredibly skilled at cracking codes and are bested only by Odd Todd.
• Cute Kitten: All of them are feline agents who just so happen to wear snazzy jackets.
• Cuteness Proximity: When Olympia lays eyes on them, she can't help but "aww" at them.
• Identically Named Group: There are numerous non-human agents at Odd Squad, but these six kittens all share the same name of "O'Fur" and four of them share the same role of cracking codes for Oprah.

Ogg

Played by: Tomaso Sanelli

One of the inhabitants of Olympia's room in "Olympia's Day", who ends up owning the entire room at the end of the episode.

• Dark Horse Victory: In "Olympia's Day", he ends up being the sole owner of Olympia's room out of sixteen agents that Olympia brings in to fill the spots, by way of Drawing Straws.
• Meaningful Name: His name — assuming it actually is Ogg and not just a moan — is an onomatopoeic spelling of his frequent moaning and groaning.
• Mellow Fellow: He is very cynical, frequently speaks in groans, and shows very little emotion. This puts him in contrast with fellow Genki Girl Olympia, whose actions in "Olympia's Day" cause her to undergo Sanity Slippage in a way that makes Ogg feel uncomfortable and threatened by her.
• Messy Hair: Has a scruffy head of brown hair.
• The Quiet One: He speaks mostly in moans and groans, and only has a sparse few lines where he actually communicates in words.

O'Brian

Played by: Kyle Breitkopf

One of the many tube operators, he gets A Day in the Limelight in "Life of O'Brian" where it's revealed he tube blocks agents for petty reasons.

• Disproportionate Retribution: Owen was trapped inside of the tubes for three days, while Octavia got trapped inside of Headquarters for a week. Why? Because they both made O'Brian mad in some way or another.
• The Gadfly: He intentionally blocks Olive from exiting the tube lobby at one point by sealing the doors shut, which only serves to make her more upset.

Villains

In General

• Affably Evil: Despite constantly causing oddness and attacking Odd Squad, most of the villains are genuinely friendly towards both each other and even Odd Squad agents. In rare cases some my even aid agents to stop threats.
• Card-Carrying Villain: All the villains in the neighborhood are completely aware of their status as Odd Squad's enemies and are mostly unashamed of it.
• Even Evil Has Standards: They have set up a "No Tatttletale Code" that prevents villains for ratting out on other villains. Yet, despite their shady, and often untrusting nature, they've never tried to break this code.
• Evil Is One Big, Happy Family: The villains seem to have it pretty well for themselves. They're more than willing to team-up, and utilize their strengths together, are loyal to one another, and even have their own estates and set of rules.
• Harmless Villain: Played straight with some (like Noisemaker) and averted with others (like Fladam). Occasionally their gadgets have harmful side-effects, but Oscar is well equipped for that. They even work together with Odd Squad sometimes to clear their (silly) names.
• Laughably Evil: Let's face it, some of the villains on the show are more comical than evil.

Major Villains

Odd Todd

Played by: Joshua Kilimnik

A former Odd Squad agent who was the best at solving many cases and winning many awards (including the one for most awards). He is really good at solving math problems in his head, leading to his successes. Eventually, he started to believe that the Odd Squad's quest to stop odd things from happening was wrong, so he started to deliberately cause odd cases to be unsolved. He got fired for this, then came back to cause a Pie-nado in HQ and re-invent himself as a villain.

• Anti-Role Model: Oh yeah, him belittling his partner Olive and letting his pride get the best of him are major reasons he got fired from the squad. That's a difference between him and Otto. They both were Olive's partner, but Otto actually cared for Olive and allows her to have a say in things. Todd on the other hand looked down on Olive, and cares more about his personal image more the his partner.
• Arc Number: His agent number is 43, and that number appears multiple times in the series.
• Benevolent Boss: For an arrogant, mischievous, chaos loving villain, he's very nice to his minions.
• Chaotic Evil: He wants to cause odd things to happen For the Evulz.
• Child Prodigy: There's a reason he was labeled as Odd Squad's best agent.
• Cloudcuckoolander: Being odd can do this to you.
• Control Freak: As a gardener.
• The Dreaded: Before his origins were revealed, many agents avoided talking about him.
• Even Evil Has Standards: in the Season 1 finale, he got freaked out by all the odd creatures released by Otto.
• Evil Genius: He's shown to be incredibly intelligent and a savvy problem solver. While he was a very successful Odd Squad agent, he's also quite ruthless, calculating and devious
• Evil Is Hammy: Loves to ham things up in nearly all of his scenes.
• Face–Heel Turn: He was a good agent until he decided to make oddness instead.
  • Heel–Face Turn: Becomes a gardener after the Season 1 finale, but has a brief He's Back! moment. Luckily, it doesn't last.
• Fallen Hero: See The Paragon Always Rebels.
• Hero's Evil Predecessor: Is this to Otto, being Olive's former partner.
• Invincible Hero: Was this before his Face–Heel Turn. He could solve any case.
• Jerkass: He was a jerk to Olive before he became evil, criticizing her habit of writing on her notebook to solve problems and calling her "Scribbles."
• Odd Name Out: All the other agents' have names starting with "O," his starts with "T."
• The Paragon Always Rebels: He was Ms. O's best agent until he decided oddness was better.
• Reformed, but Not Tamed: Shows a bit of his former self as a gardener.
• Smug Snake: Being one of the smartest agents Odd Squad ever had, naturally he often sees himself as too good for rules and can be very arrogant, not paying attention to anyone other than himself. "The O Games" is a perfect example of this in action.
• Walking Spoiler: His existence is foreshadowed a couple of times in Season 1, but he never physically appears until midway through the season, and that's when things take a darker turn.

Otis' Duck Family

One of the Greater Scope Villains of Season 2 and Otis's adoptive family.

• Didn't Think This Through: Brother Quack decided to create a machine that would move the Earth closer to the sun so he and the other ducks could have the pond all to themselves... not considering the fact that doing so would fry everyone on Earth alive, including the Ducks, so his plan never would have worked out.
• Feathered Fiend: Their entire goal is to take over as many ponds in the world as they can...even if it means moving the Sun closer to Earth in order to achieve it.
• Heel–Face Turn: It's implied that Brother Quack makes one, as he reconciles with Otis at the end of the Season 2 finale.
• Supervillain Lair: They have one in the form of a large, spacious barn, which also served as Otis's home.
• Walking Spoiler: Their existence isn't revealed until the Season 2 finale, where we get to see why Otis is the way he is.

Minor Villains

Shapeshifter

Played by: Laura Landauer, Aja Neinstein (young)

One of the Squad's most consistent enemies.

• I Know What You Fear: In "The Briefcase", she turns her entire head into a pie in order to scare Olive, who is afraid of them. Later on, she turns Ms. O's briefcase into a pie in another attempt to scare the Investigation agent.
• Invocation: She usually prefaces her transformations with ¨I'm a...(something). I'M A ...(SOMETHING)!¨
• Sci-Fi Bob Haircut: Hers is bright blue.
• Shapeshifter Baggage: Though she is said to retain the same weight, she has been seen to turn into things like a rocket and butterfly and still fly away.
• Shapeshifter Default Form: A glowing human woman with a bob cut and bright white pictures as a body.
• Shapeshifting Sound: She transforms with a flash of light and a whooshing sound effect.
• Smug Snake: She's infamous for her serious level of pride which often leads to agents using it against her and taking her down.

President Obbs

Played by: Jaedon Siewert

The President of the Scientists and the head of the Science department. Although he appears as a strong leader initially, it's soon revealed that he has...ulterior motives for the Scientists he leads.

• Bad Boss: Well yeah, if brainwashing all of the Scientists he rules is any indication.
• Bungled Hypnotism: He's good at brainwashing his Scientists. Getting them to do his bidding, however, is another story entirely.
  "How are you suddenly all not smart after I controlled your minds?!"
• Dude, Where's My Respect?: The reason why he's a villain to begin with. He believes that Investigation agents get all the credit for solving oddness while Scientists — the ones responsible for building the gadgets that agents need in order to solve oddness — get no credit at all. However, he is in the minority on this opinion, as when he contacted Scientists and explained his strife, they disagreed with him, stating that they like helping Investigation agents and that they're all a part of the same team. This is the breaking point for him, as he proceeds to use mind control on every Scientist under him so he can destroy Odd Squad as revenge.
• Enfant Terrible: Following in the footsteps of other kid villains like Odd Todd. Especially notable is that he managed to put Oprah, one of the strongest characters in the franchise, under mind control, although she and Oscar were outnumbered so she couldn't attack Obbs nor the Scientists he controls.
• Evil Genius: He's the President of the Scientists and serves as the Big Bad of "Oscar Strikes Back".
• Hazy-Feel Turn: At the end of "Oscar Strikes Back", he tells Owen and Ohio that he'll just continue to be a villain, but when handed a brochure for Todd's Life of Grime Villain Rehab, he looks at it and gives a shrug before walking away. Since he doesn't make any appearances in any future episodes nor is he mentioned, it's unknown if he's still on the side of evil or is in Todd's Villain Rehab.
• Hoist by His Own Petard: He ends up being defeated by Oona combining gadgets to make a gadget that can override his mind control. She states that she'll use it to bring all the brainwashed agents under her control and rule the world (the prospect of which appears to terrify him, and rightfully so, given her Cute But Psycho personality), but then says she's only kidding and smashes the gadget on the table to bring everyone back to normal.
• Hypno Trinket: For Lab-Con, he designed pins that, when worn and activated, put the wearer under mind control.
• The Leader: He is the head of the Science department at Odd Squad and serves as the President of the Scientists. This is despite Oscar having founded the department to begin with, although he does get promoted to the position eventually.
• Long Game: It's implied that Obbs had been planning to take over Odd Squad using mind control for years, but for some reason, he never got around to putting it in action until Lab-Con.
• The Mentor: A deleted scene from the script of "Oscar Strikes Back" reveals that he serves as a teacher for Scientists-in-training at the Odd Squad Academy. Given his status, though, it's likely he is an Evil Teacher.
• Mind-Control Device: He controls his Scientists using a remote, which is classified as a gadget.
• Our Presidents Are Different: While not a president of a country, he is referred to as the "President of the Scientists" and rules over an entire department. He is a mix of the President Evil and the President Scheming types.
• Surrounded by Idiots: Apart from a small handful of instances, he just can't get his mind-controlled Scientists to do anything he wishes.
• Take Over the World: What he hopes to do once he destroys Odd Squad. He's even willing to go one step further and conquer any planets that have life on them, stating that he has a hunch about Neptune in particular.
• Turn in Your Badge: Once Oona frees the Scientists from his mind control, Obbs is forced to give his badge to Owen and Ohio.
• Vile Villain, Saccharine Show: Obbs is a fearful Enfant Terrible who wishes to destroy Odd Squad with the help of his lackeys, the Scientists he leads. Said lackeys, however, get their IQ points significantly reduced when mind-controlled, which frustrates Obbs.
• Waistcoat of Style: Wears a green one under his labcoat, in contrast to the other Scientists' white ones.
• Walking Spoiler: It's hard to bring him up without also bringing up the entire events of "Oscar Strikes Back", especially Oscar being promoted in place of him.
• invoked What Could Have Been: According to the pink draft of the script for "Oscar Strikes Back", Obbs was originally meant to be a girl who wore a turtleneck sweater instead of a green vest. The script also described him as "like an evil Tony Stark."
  • Likewise, the episode also would have had him serve as a teacher for Scientists-in-training that attended the Odd Squad Academy.
  • The announcer that introduces him refers to him as "the greatest Scientist that ever lived" in the pink draft of the script for the episode, which adds to his "showy" personality that was kept in the final product.
• What Happened to the Mouse?: He's given a brochure to Todd's Life of Grime following his firing, but we never see nor hear of him again.

Jamie Jam

Played by: Ashley Comeau

A villainess whose specialty is jam. She enjoys splattering people and objects with it, and is a frequently recurring foe in Odd Squad's Rogues Gallery.

• Alien Blood: An interview with Christine Toye, the show's costume designer, has her mentioning a theory that Jamie Jam is "made up of jam on the inside with a human crust". Whether this is actually true or not, however, is unknown.
• Alliterative Name: Goes along with the naming theme of other villains having the same kind of name.
• Batman Gambit: "20 Questions" has her exploiting Oprah's juice addiction by giving her a juice box in exchange for allowing agents to ask villains only twenty yes-or-no questions. It works like an absolute charm.
  • The same episode has her giving an addendum to her deal — allowing the rule to be extended to villains' mothers as well, so that any questions they are asked count towards the overall total. Oprah declines and closes her eyes so she's not tempted again, but this doesn't sway Jamie, as she has Father Time win the Director over by placing another juice box in front of her and allowing her to smell the West Indonesian guava it was made with. It ends up working yet again.
• Card-Carrying Villain: She's not shy about letting citizens know she's a villain, treating her odd crimes like a provided service.
• Clashing Cousins: She and Marty Marmalade don't get along well with each other.
• Enemy Mine: "Villains in Need Are Villains Indeed" has her teaming up with Odd Squad, along with the Noisemaker and Mr. Lightning, to stop a rampaging indestructible robot of her (partial) creation.
• Even Evil Has Loved Ones: In "Flawed Squad", she mentions taking her nephews to the museum next Saturday, showing how much she can prioritize them over attacking Odd Squad.
• Gadgeteer Genius: Yes, if the robot she built in "Villains in Need Are Villains In Need" is any indication.
• Heel–Face Revolving Door: At the end of "Mid-Day in the Garden of Good and Odd", she is shown working in Todd's garden. Later episodes would have her returning to villainy, "Odds and Ends" would show her as a part of Odd Todd's Home for Villains, and Season 3 would have her going right back to being a villain.
• Insistent Terminology: Often corrects those who say she deals in jelly by saying it's jam, and then comparing the two foods.
• Laughing at Your Own Jokes: Her debut episode has her making various jam puns and cracking herself up with them.
• The Leader: Becomes this in "Villains in Need Are Villains Indeed".
• Precision F-Strike: Subverted. In "Villain Networking", she seemingly says "damn" to the first Sister Sally just before attacking her, but closer listening reveals that she's actually saying "jam". Her saying "damn" is a subtitle error from PBS Kids.
• Purple Is Powerful: She wears predominantly purple and has been shown to be pretty smart in outwitting Odd Squad agents.
• Remember the New Guy?: Despite her debuting in Season 2, she is established as a recognized villain.
• Robot Buddy: Jamie has a very strong attachment to Benny, the robot she built in "Villains in Need Are Villains Indeed". When she and Otis go inside him in an attempt to stop him, she asks the agent for a moment alone with him before she leaves.
• Taught by Experience: She's been caught by Odd Squad so many times that she ends up giving tips to other villains for how to avoid getting caught themselves. All of them lampshade various villain-oriented tropes (Evil Gloating, Meaningful Name, etc.)
• Telepathy: Gains this power for the sake of the Rule of Funny in "Villains Helping Villains".
• Trademark Favorite Food: Jam, of course. Not jelly.
• Tricked-Out Gloves: Jamie Jam wears a pair of gloves that she uses to attack with. They are activated in the same way one would open a jar of jam — she twists the lids attached to them and gets to blasting.
• Villainous Friendship: Seems to be good friends with Mr. Lightning and the Noisemaker.
• Villain Song: "When You're Not Causing Oddness", a duet with her cousin Marty Marmalade that focuses on what villains can do when not committing odd crimes.
  • There's also "Say You Did Wrong" from "Odds and Ends", which is a Broadway-style piece that's about villains admitting they've done wrong and making Heel-Face Turns.

Fladam

Played by: Martin Roach

A villain who has a deep hatred of cubes. His power is the ability to flatten people and objects that are three-dimensional using his trademark sunglasses.

• Absurd Phobia: The end of "Flatastrophe" seems to imply that Fladam doesn't just hate cubes, he's outright afraid of them.
• Bizarre Taste in Food: Fladam likes ice cream sandwiches. However, his preferred idea of an ice cream sandwich is a scoop of ice cream placed in between two pieces of bread, and every time he asks for one, he gets a typical ice cream sandwich.
• Comic-Book Fantasy Casting: Looks very much like will.i.am, right down to the uniquely-designed sunglasses.
• Copycat Mockery: Uses this against Polly Graph in "Flatastrophe" when he threatens to flatten her cube-shaped seats.
  Polly Graph: [whining] No, please! My customers won't have anywhere to sit!
  Fladam: Nooo, please! [Evil Laugh]
• Freudian Excuse: He developed a vendetta against cubes because as a child, he ran through his playroom and stepped on a toy block. Olive wastes absolutely no time in asking him:
  Olive: Are you sure it was the cube's fault? 'Cause it kinda sounds like you're clumsy-
  Fladam: [defensively] I am...not!
• Heel–Face Revolving Door: Although "Flatastrophe" showed him getting treatment from Odd Squad in order to get over his fear of cubes, later episodes show him returning to villainy.
• Paper People: Discovers that he has the power to turn people into these in "Flatastrophe" when he aims for one of Polly Graph's chairs and ends up attacking Olive instead.
• Punny Name: His name is a combination of his real name, Adam, and his schtick of flattening things.
• Remember the New Guy?: Averted. Olive and Otto have no idea who Fladam is before meeting him for the first time at Polly Graph's lemonade stand.
• Sinister Geometry: He's not a geometric figure, but he can destroy cubes and make things two-dimensional using his sunglasses.
• Sinister Shades: His sunglasses can flatten both people and objects by firing blue beams at them. They can also restore two-dimensional figures as well, as Precinct 13579 manages to figure out.
• Sore Loser: His reaction to losing the rock-paper-scissors competition to Kooky Clown (or who he thought was Kooky)? Attempt to use his powers to flatten her, and inflict serious harm. Even some of the other villains are against this.
• Weaksauce Weakness: A single knock to the neck by a folded-up Olive is enough to knock him down and leave him too stunned to fight back.
• Would Hurt a Child: His discovery of his power to flatten people as well as objects comes after Olive is flattened by him during a Diving Save.
  • He also has no problem threatening to hurt Kooky Clown (or whom he thinks is Kooky, anyway), who appears to be a child, in "Undercover Olive" after she beats him at rock-paper-scissors. It takes the combined might of Even Steven and Jellybean Joe just to restrain him.

Mr. Lightning

Played by: Joseph Motiki

A recurring villain with electric powers.

• Electric Black Guy: Pretty much fits the bill in every aspect aside from the "superhero" portion. His lightning attacks are strong enough to cut through solid dirt and brick with ease.
• Evil Laugh: Doesn't do this often, but "New Jacket Required" has him pulling off a pretty solid one after Olympia shows him the manual of Otis's new jacket and he destroys it.
• Gadgeteer Genius: With the help of Jamie Jam and the Noisemaker, he's able to build a Humongous Mecha in "Villains in Need Are Villains Indeed".
  • "New Jacket Required" has him building a MacGuffin machine that "can do many different evil things", according to Oprah. What it does, exactly, isn't elaborated on any further than that, but it apparently requires three stuffed folders and two hours just to explain.
• Hand Rubbing: Does this every time before he attacks.
• Hell-Bent for Leather: He dons a black leather jacket with lightning-bolt emblems on his arms.
• Kiai: Often punctuates his attacks with "Pa-kow!"
• Shock and Awe: His main powers consist of shooting lightning out of his hands, but he can also generate thunder. He's powerful enough to restore a bus's entire battery meter.
• Villains Out Shopping: In many of his appearances, he is often seen running errands such as going to the mall or getting his hair done at the barbershop.

Kevin Noisemaker

Played by: David Tompa, James Hartnett (Noisemaker II), Will Bowes (Noisemaker III)

A villain whose ultimate goal is to fill the entire world with a variety of odd noises.

• Ancestral Name: If the credits of "Oscar of All Trades" and "Undercover Olive" are to be believed, he is the ancestor of Noisemaker II and Noisemaker III. ^note This could also be a way to differentiate between each actor playing the character, but this is never explained.
• Badass Cape: He dons a yellow one that is made by the Stitcher in "Who is Agent Otis?"
• Befriending the Enemy: Played with. He treats Otis as a best friend rather than an enemy, but the friendship is entirely one-sided on his end.
• Costume Evolution: In "Who is Agent Otis?", his outfit has gone from being predominantly brown to yellow. He also wears a cape.
• Court Jester: Has the appearance of one. He can even juggle twenty balls at once.
• Heel–Face Turn: Subverted. He nearly turns to the side of good in "Otis's Day" by going into the Villain Protection Program, but backs out because he doesn't want to lose Otis as a friend and wants to stay on the side of villainy.
• I Surrender, Suckers: In "Flawed Squad", he initially admits defeat when Olympia and Otis order him and the other villains to exit the Arts and Crafts Room, but then shoves a slew of instruments into the agents' hands before taking off.
• Keeping Secrets Sucks: He is unable to keep a secret. As a result, Jamie Jam and Mr. Lightning prefer to keep him out of the loop when it comes to secretive and confidential matters.
• Last-Name Basis: He is always referred to by his last name, "Noisemaker". It's not until "Who is Agent Otis?" that we learn his full name is Kevin Noisemaker.
• Musical Assassin: He wields a Clarinet of Chaos and a Fiddle of Fear, among many other instruments.
• One-Man Band: His entire outfit is filled with instruments.
• Sweet Baker: Inverted and downplayed. His first appearance in "Odd Outbreak" involves him crafting chocolates that, when eaten, cause the consumers to make loud and odd noises every time they open their mouth.
• Unexplained Accent: The show (mostly) takes place in Canada, but the Noisemaker speaks with a German accent.
• Villainous Friendship: Seems to be good friends with Mr. Lightning and Jamie Jam, according to "Villains in Need Are Villains Indeed".
• With Catlike Tread: When your entire body is covered with instruments that move when you do, "stealth" is a bit of a foreign concept. "Flawed Squad" has Jamie Jam realizing this, and exploiting it by using him as a distraction.
• Witness Protection: He nearly goes into Odd Squad's Villain Protection Program for the second time around in "Otis's Day", but losing Otis as a friend scares him out of it.

The Puppy Master

Played by: Starr Domingue

A villainess who specializes in puppies — more specifically, the act of turning people into puppies.

• Attack of the 50-Foot Whatever: In "The Cherry-on-Top-inator", her plan is to make a puppy grow big enough so that it treats the planet Earth like a slipper and chew it up.
• Color-Coded for Your Convenience: When she uses Tube Travel to exit Precinct 13579 in "And Then They Were Puppies", she travels in a clear transparent ball instead of a colored transparent one.
• Doomsday Device: Although she has a smaller and more portable one that she uses in later episodes, her ultimate plan in her debut episode is to use a gigantic puppy ray she had built to turn everyone in the entire world into puppies.
• Even Bad Men Love Their Mamas: In "Total Zeroes", the first thing she does when she finds out she's ranked #12 on the 2013 Most Odd List is call up her mother to share the good news. Once she congratulates her, she asks her to put her father on the line so he can receive the good news as well.
• Everything's Precious with Puppies: She's called "The Puppy Master" for a very good reason.
• Evil Is Hammy: Make no mistake, she can chew the scenery when she wants to.
• Gadgeteer Genius: Known enough about gadgetry to build both a handheld puppy ray that turns people into puppies, and a gigantic version of the ray that has enough power to zap the entire world and turn the people within it into puppies.
• The Leader: Serves as the leader of the villain raid to steal the Golden Sundial in "Odd Together Now".
• Lovely Assistant: Briefly becomes the magician's assistant to Osmerelda in "Ahead of the Times".
• Near-Villain Victory: Obtains this in "And Then They Were Puppies" when she manages to turn Otis and Olympia into puppies. The only reason she didn't get a chance to zap the rest of the people in the world with her gigantic puppy ray is because she forgot to factor in resident Confusion Fu master Ohlm.
• One-Steve Limit: Downplayed. Her name is very similar to that of The Puppet Master from the Season 1 episode "Puppet Show" (to the extent that Otis has to ask Oprah if she meant The Puppet Master was in HQ in "And Then They Were Puppies"), but they are in no way related.
• Sassy Black Woman: She can get this way sometimes.
  The Puppy Master: And bring him a tuna melt! He eats whatever I tell him to eat!
• Supervillain Lair: Her lair looks like an old observatory, but with a large dog bone placed on top.
• Villain Cred: The Series Finale, "Odd Together Now", reveals that the reason she wants to steal the Golden Sundial is so she can get respect from other villains.

Others

Other Characters

Polly Graph

Played by: Ava Preston, Quinn McColgan (pilot)

The town's resident graph expert who is a reliable ally of Precinct 13579. She sells hot chocolate and lemonade, and has a very keen eye for quality.

• Aloof Ally: Downplayed. Polly Graph isn't an employee of Odd Squad and doesn't fight oddness alongside agents, but is always willing to help agents when they come to her stand. She also comes to Precinct 13579 often to settle conflicts.
• Girlish Pigtails: She often wears her hair in these, which are secured by pink bows.
• Pink Means Feminine: She likes the color pink.
• Punny Name: A polygraph is a lie detector, which references her knowledge and usage of graphs.
• Put on a Bus: She doesn't have any physical speaking appearances after The Movie. However, a still image of her from "Disorder in the Court" appears in "Raising the Bar".
• Quality over Quantity: Polly Graph prides herself on quality when it comes to her lemonade, and has a keen eye for it.
• Secret Underground Passage: Polly houses the entrance to one leading to Precinct 13579's headquarters, which was dug by Ms. O.
• Speaks Fluent Animal: In "Bad Lemonade", she learns how to speak pigeon, and summons a flock of them to drive Odd Todd away from his own stand.
• Will Not Tell a Lie: In the original pilot for the show, Polly tells Olive and Otto that she's not the number hog, and pulls out a graph that shows how many times she's ever lied. The graph is completely empty.
• Young Entrepreneur: She sells both hot chocolate and lemonade from a stand set up at the end of her driveway. "Bad Lemonade" reveals that she treats her sales as Serious Business and views her stand as a legitimate business.

Amanda

Olympia's best friend from outside of Odd Squad, who is introduced in OddTube.

• Best Friend: She is described as Olympia's best friend outside of work and is very supportive of her.
• Canon Foreigner: She was created solely for the web series and isn't seen in the show.
• Cloudcuckoolander's Minder: Subtly implied to be this for Olympia in "Pandas", since Olympia is a Genki Girl and a severe Workaholic.
• Pink Means Feminine: She wears a pink shirt under a pair of overalls.
• Single Serving Friend: While she does make brief cameos in OddTube via mentions (and also makes a cameo on the web series' website as a picture in Olympia's locker), "The Ball Pit" is her only physical appearance and she doesn't appear in the show. Despite this, she is referred to as one of Olympia's closest friends.

Big Red

Played by: Hayden Landolt

A civilian who is the inventor and builder of the Odd Squad tube system. He lived in Toronto back in 1870.

• Fiery Redhead: He's a subversion, having red hair but being generally laid-back and mellow.
• Gadgeteer Genius: He's the creator of the Odd Squad tube system, which he digs as a token of thanks to Oprah and O'Donahue for helping him get back his mailboxes.
• Mistaken for Thief: He is initially suspected by Olga and O'Donahue as having stolen Oprah's fruit. However, he turns out to not be the culprit when he becomes a victim of the criminal's robbery and has some of his mailboxes stolen.
• Red and Black and Evil All Over: Subverted. Big Red wears a red longcoat with a red belt and undershirt and wears a red-and-black fur collar, but isn't a villain nor is he evil — he's a victim of oddness who helps Oprah and O'Donahue out.
• Tube Travel: He creates the Odd Squad tube system to repay Oprah and O'Donahue for helping him.
• You Are the New Trend: Big Red having red hair and being the creator of Tube Travel for Precinct 13579's agents sparked a sort of unintentional trend where every tube operator at the precinct has red hair. Whether this is coincidence or it was intentional is unknown.

Coach Roberts

Played by: Darryl Hinds

The coach of the various Burly Bears sports teams in town whom Olive idolizes.

• Beyond the Impossible: He's the coach of the Burly Bears basketball, soccer and hockey teams, among many other sports. How he has time to coach all of them is a mystery, but even in a show full of oddities, one can't deny that it's an impossible feat.
• Butt-Monkey: He is a very frequent client of Precinct 13579, often having things stolen from him or being attacked by odd creatures.
• Hologram: In "The Potato Ultimato", he appears as a hologram in the Cave of Your Least-Greatest Fears, begging Olive to help him out with his fifteen concurring games after all his players become hurt.
• The Knights Who Say "Squee!": Downplayed. While he isn't a complete Fanboy like Otto, Coach Roberts enjoys Soundcheck and their music. Coincidentally enough, Olive, who idolizes him, ends up liking the band after also going to see a concert of theirs at the mall.
• Mentor Archetype: It's revealed in "Disorder in the Court" that he is Olive's personal javelin coach, as she attends javelin practice with him.

Delivery Debbie

Played by: Ashley Botting

The owner of Debbie's Pizzeria and a frequent client of Odd Squad.

• 30 Minutes, or It's Free!: Debbie promises that pizza is delivered to dine-in customers in one minute or less. However, when ordering delivery, this policy doesn't seem to apply.
• Adults Are Useless: Largely averted. Debbie is one of the most intelligent adults on the show, but she isn't without her moments of idiocy, such as in "The Voice" when she doesn't suspect "Ms. O's" pizza delivery instructions to be faulty.
• Alliterative Name: Delivery Debbie.
• Bad "Bad Acting": While "Safe House in the Woods" reveals that she is taking acting classes, she turns out to be a terrible actor and fails in convincing Ozlyn to join the Security department.
• Bad Luck Charm: In "Show Me the Money", Debbie has a string of bad luck caused by an unlucky nickel that Otis gives her in order to pay for his and Olympia's pizza as well as the latter's pack of gum. Once the nickel is off her person, the bad luck stops.
• Crazy-Prepared: In addition to a fanny pack that she keeps on her at all times, Debbie also carries items in her pizza delivery bag that she sells to customers, such as a pencil, a pack of gum, and a pair of googly-eyes that doubles as a calculator.
• Does Not Like Spam: While Debbie is (quite obviously) a fan of pizza, she refuses to eat pizza crusts.
• Jingle: Her pizzeria has one, which Olive and Otto know by heart: "Call Delivery Debbie, the best pizza you'll find! Call Debbie, she's one of a kind! Order today!" It was later updated to say "four of a kind" with the addition of her clones, and the melody was reworked into the jingle for her and Doug's combined business as well as the jingle for Doug's standalone business later on.
• Made of Iron: In Odd Squad: The Movie, Debbie manages to survive on nothing but a single large pizza with nothing to drink for a month, and while in a bad state of health, she is still alive and standing by the time Otis and Olympia happen upon her.
• Me's a Crowd: In "Double Trouble", Debbie becomes overworked at her pizzeria and wishes that there were more of her to go around. She ends up inadvertently creating three clones of her which wreak havoc across town by way of delivering the wrong pizzas to the wrong customers. Eventually the clones are employed under the original Debbie, but aren't seen again in subsequent episodes.
• Nervous Wreck: Becomes this in "The Breakfast Club" when she has to go and directly confront the titular villain group, complete with Acting Unnatural, to such an extent that she's unable to answer her phone and has to rely on Ms. O giving her a cue card.
• Nice Girl: She's generally nice to Odd Squad and to her customers, and isn't even that much of a Jerkass towards her rival Doug.
• Offscreen Teleportation: She has managed to pull this off in a few episodes, such as in "Oscar the Couch" and "The Breakfast Club".
• Only Known by Their Nickname: Delivery Debbie is often referred to as "Debbie". On occasion, people will refer to her as "Delivery Debbie", but only Doug explicitly refers to her by her full first name, "Deborah", in "Safe House in the Woods".
• Only Shop in Town: Debbie's Pizzeria is the only one of its kind in town.
• Pink Girl, Blue Boy: She wears red to contrast with Delivery Doug wearing blue.
• Put on a Bus: She doesn't make any more appearances after Season 2, but her pizzeria does make a cameo in the Couch Gag of the Season 3 episode "The Thrill of the Face".
• Red Is Heroic: Debbie wears predominantly red clothing, and is an ally of Odd Squad's.
• Severely Specialized Store: At the end of "Mystic Egg Pizza", she and Doug set aside their rivalry and open up a restaurant that only sells one thing: egg salad pizzas. However, the store was dropped in future episodes.
• The Rival: To Delivery Doug, who sells egg salad sandwiches. Although they eventually drop their rivalry by the events of "Mystic Egg Pizza".
• Terrible Artist: While she is taking art classes as of "By the Book", her art still looks terrible, which doesn't help Olive's case. By "The Breakfast Club", however, she gets much better at drawing.
• Written by Cast Member: "Safe House in the Woods" is written by Ashley Botting, who portrays Debbie. Likewise, Debbie herself also makes a prominent appearance in the episode.

Delivery Doug

Played by: Ali Hassan

The owner of Delivery Doug's Egg Salad Sandwiches and Delivery Debbie's rival.

• Adults Are Useless: Doug definitely isn't the smartest adult in the show, being dumber than his rival Debbie, but he does have somewhat good intentions and manages to be of helpful assistance to Odd Squad on a couple occasions.
• The Alleged Car: Drives a station wagon dubbed the Eggmobile that looks fine on the outside but has numerous problems on the inside, such as non-functional windows, a non-functional front passenger door, and a lingering stench of egg.
• Alliterative Name: Delivery Doug.
• Bad "Bad Acting": Although he got into theater for a short while before getting into the egg salad business, his acting is incredibly stilted and he even gets a short bout of stage fright in "The Deposit Slip-Up" when playing the role of Pete, the Villains' Vault security guard.
• Basement-Dweller: He runs his business from his mother's basement, although it's unknown whether he lives at his mother's house or if he has his own place.
• Cheaters Never Prosper: "Who Let the Doug Out?" reveals that Doug used to take part in a secret egg-racing club, but was banned from racing due to cheating by taping an egg to a spoon.
• Cordon Bleugh Chef: Doug can make egg salad sandwiches that look pretty appetizing. The only problem is that there's not much of a market for egg salad sandwiches, whether it's in Toronto or in the Arctic. Almost no one likes them and almost no one wants to eat them, and as a result, his business isn't as much of a hit as Delivery Debbie's. When he joins forces with Debbie and the two create egg salad pizza, it's such an awful combination that not even Otto — known for being a Supreme Chef and a Big Eater himself — can stomach it.
  • To say nothing of the methods he employs to make his egg salad sandwiches, all of which are incredibly unconventional and illogical.
    • He keeps his sandwiches on the floor of his mother's basement to keep them cool.
    • He only uses the two middle slices of a bread loaf for his sandwiches, because they're the squishiest slices.
    • He uses an entire jar of mayonnaise to make two sandwiches, and retrieves it from a washer at a local dry-cleaning place.
    • He never changes the water stored in the barrels he has, which he uses to boil the eggs themselves, because it locks in their flavor.
    • According to him, his egg salad recipe is a secret recipe despite many knowing about it and many finding it unappetizing, complete with Secret Ingredients needed to make it.
• Dreadful Musician: Doug has recorded quite a few songs, and all of them have about as much quality as a dumpster full of trash. If the pop song he recorded with his mother is any indication, a lack of musical talent runs in the family.
• Evil Twin: The security guard protecting the Villains' Vault in "The Deposit Slip-Up" is a spitting image of Doug, which Precinct 13579 exploits in the episode as they try to fool Symmetric Al into giving them Oprah's Jet Pack back. However, Doug himself doesn't see the similarities.
• Gadgeteer Genius: Some time after Doug fired Randall, he built him a goat-to-human translator device that allows him to speak.
• House Squatting: In "Safe House in the Woods", it's revealed that Doug has been using an Odd Squad-owned house to make his egg salad sandwiches in without gaining permission from (presumably) Oprah, since he never asked. Once Owen finds this out, he's quick to tell him that he can't stay, but he decides to compromise and ask if he can stay until the nasty thunderstorm outside passes. At the end of the episode, Ozlyn tells Owen to just let him stay at the house, and the Security agent agrees.
• Leitmotif: Since "Mystic Egg Pizza", his Piss-Take Rap song "All I Really Want is Eggs" has been commonly associated with him.
• The Millstone: If he's forced to work with someone, whether it be Delivery Debbie or Odd Squad, expect him to be a complete hindrance rather than a helpful force. Even when he tries to help, he just ends up making things worse for everyone involved.
• Pink Girl, Blue Boy: He wears blue while Delivery Debbie wears red.
• Pungeon Master: He has a fondness for making egg-related puns.
• Reassigned to Antarctica: More reassigned in the meta sense, but "Teach a Man to Ice Fish" has him opening two restaurant locations in the Arctic that, naturally, don't get much business.
• The Rival: To Delivery Debbie, although they (mostly) put aside their differences by "Mystic Egg Pizza".
• Small Name, Big Ego: Boy howdy. Doug believes that his business is a "successful empire" and is incredibly proud of what he does no matter what other people say. Debbie even accuses him of being jealous over her more successful pizza business at one point.
  "Hi! I'm Delivery Doug. You may know me as the Egg Salad Sandwich King. If you don't, where have ya been?!"
• The Thing That Would Not Leave: He becomes this in "Who Let the Doug Out?" when his mother's basement floods and he is forced to relocate his business to Precinct 13579. Unlike most examples, however, he's well aware that he's a nuisance to Odd Squad and exploits it in order to have Olympia and Otis compete in an egg race in his place.
• Whale Egg: When running his back-alley restaurant, Doug is shown to have a goat assistant named Randall, who lays the eggs that Doug uses in his egg salad recipes. Then he's posed the question of why he doesn't just use chicken eggs for his recipes, and decides to lay Randall off.

Mathroom / Carol

^{Click to see the Mathroom in the pilot.}

^{Click to see Carol in the present day.}

^{Click to see Carol as seen in The Eighties.}

Voiced by: T.J. McGibbon

Initially created by Oprah in 1870 and dubbed the "Mathematical Figuring-Out Locale", the Mathroom is an entity of sorts that Odd Squad agents go to when they need help solving mathematical problems. Its sole native occupant is Carol, a sentient paper fortune teller.

• Extra Digits: The Mathroom has the ability to give a person extra limbs, like fingers, in order to help them solve a problem.
• Hidden Depths: The episode "Not So Splash" reveals that in addition to conjuring up numbers and other mathematical equations, it can also pull up profiles of various people when asked.
• Magical Land: This is perhaps the best way to sum up what the Mathroom is. It's a world only known and only used by Odd Squad agents that isn't like Earth at all, with Otto describing it as "a paper world, full of math". It's only comprised of paper fortune tellers with a spherical construct and a platform in the shape of the Investigation symbol functioning as a central hub of sorts, and the fortune tellers have the ability to conjure up anything mathematical-related that the user desires to see. One of them, Carol, is sentient, but it's never explained how she gained her sentience from the time the Mathroom was built in 1870 to the present day.
• Put on a Bus: "Not So Splash" is the Mathroom's, and Carol's final episode appearance, and they're never seen again for the rest of the season, nor are they in Season 2. The Season 3 episode "Welcome to Odd Squad", however, does make a mention of them and shows a scene in "Bad Luck Bears" of Olive and Otto going to the Mathroom, but it's for pure Discontinuity Nod purposes and they are cited as being ancient technology when compared to the smartwatches, whioh debuted in Season 2.
• Toilet Humor: Since the Mathroom is a Pun on the word "bathroom", agents who go to it often state that they "really need to go to the Mathroom". The episode "Not So Splash" implies that it serves as a magical equivalent to a one-toilet bathroom, only without...well, the toilet.
• World Shapes: The core of the Mathroom takes on a spherical shape.

Rivka and Baby Genius

Rivka played by: Meghan Allen

A nanny-and-child duo who often assists Odd Squad in exchange for various favors. Baby Genius is the spearhead of the duo, and agents often go to him for objects or hints they need to acquire to solve cases, with Rivka translating his baby talk for him as needed.

• Abandoned Warehouse: They linger around and operate in the hallway of one. Mysteriously, it looks similar to the hallway shown in Precinct 13579 in a few episodes, like "Robert Plant" and "6:00 to 6:05", though this could just be due to it being a Recycled Set.
• Ambiguously Evil: By Rivka's own admission in "Jinx", Baby Genius is a villain, which is exemplified by him enjoying things like seeing Olive and Otto intentionally hurt themselves repeatedly. However, he can, he will, and he does give agents what they need so long as they appease to his whims and desires, and is even well-behaved around Olympia and Otis when they end up becoming his temporary babysitter, giving them the answer they need to stop Marty Marmalade without the need for a bribe. It's hard to classify him as either an ally of Odd Squad's or as a villain in their Rogues Gallery. The same trope also applies to Rivka, who generally goes along with what Baby Genius says because she's his translator.
• Bizarre Taste in Food: It's not enough for Baby Genius to drink the milk of cows or humans — he has to go one step further and drink the milk of giraffes.
• Brainy Baby: He may speak mainly in baby talk, but Baby Genius is exceptionally smart in the subject of mathematics all the same. He is one of the only villains in the entire franchise who actually has a good grasp on mathematics, as opposed to other villains who have very little knowledge on it.
• Comically Small Bribe: Pretty much a large majority of what the agents bring to Baby Genius amounts to these. Olive even resorts to pocket lint in "My Better Half", which works, but when she tries the same tactic again in "The Odd Antidote", Rivka tells her that pocket lint was "so last month".
• Creepy Child: Baby Genius is, by Rivka's own words in "Jinx", a villainous baby who takes immense joy in seeing agents intentionally hurt themselves and mostly hangs around in a dark and dingy warehouse with Rivka herself.
• Creepy Good: Both Rivka and Baby Genius (or in the latter's case, the stroller he sits in) are decked entirely in black, and roam about in an Abandoned Warehouse with the lights off at all times. This is mostly why agents believe they are The Dreaded and want nothing to do with them unless it's a last resort. The trope ends up being invoked in "Ocean and the Fly", where Rivka states that she kept the lights off in the warehouse because she thought agents liked it when she and Baby Genius were dark and mysterious.
• Deadpan Snarker: Rivka can snark at certain times.
  Olive: How about a comb?
  Rivka: Great, a comb! So Baby can comb all the hair he doesn't have.
• The Dreaded: In the beginning of Season 1, Rivka and Baby Genius were people to be feared — and feared they were, even to those like Olive. It isn't until Season 2 that this trope becomes averted, as agents become more comfortable with seeing them and show no signs of fear at all.
  • The pilot takes this a step further by having the characters' Establishing Character Moments be Rivka wheeling Baby Genius's stroller directly over the neck of a stuffed toy, followed by a terrified Olive and Otto slowly creeping towards them and inquiring about a number hog to the sole tune of a heartbeat.
• Hidden Depths:
  • Some of the bribes that Baby Genius accepts can be rather unusual, such as Otto's birthday party invitation in the pilot or Olive's pocket lint in "My Better Half".
  • In "Two Agents and a Baby", Rivka goes for a pilot license and obtains it in the span of one afternoon. Said license allows her to operate Baby Genius's stroller, which has rocket thrusters built in that enable it to fly.
• Iconic Item: For Baby Genius, a yellow-and-red baby rattle with a white handle is his distinctive item. Although he's not actually seen with it, agents wave it around to indicate when someone has to go visit him, followed by said someone freaking out.
• Insistent Appellation: Rivka is often referred to as "Your Excellency", even though she holds no position of power, whether above them in Odd Squad or otherwise.
• Older Than They Look: Considering Ms. O mentioned that Rivka and Baby Genius have been aiding Odd Squad for years, realistically Baby Genius shouldn't be a baby at that point. No explanation is given to why he still is.
• Stealth Hi/Bye: Many characters in the show have this ability, but both Rivka and Baby Genius are the only ones to employ it as part of the spooky ambience they give off, rather than due to the Rule of Funny. They will, however, sometimes announce their presences by making noise beforehand, such as causing cans to spill and clatter or by way of Baby Genius giggling and cooing.
• Unexplained Accent: Rivka has a distinct Russian accent, but operates exclusively in Toronto.
• Voice for the Voiceless: Rivka serves as this for Baby Genius, who despite being able to speak, prefers not to, translating his mannerisms and providing his requests.

Odd Squad: The Movie Characters

Weird Tom

^{Click to see him as an Odd Squad agent-in-training.}

^{Click to see him as an honorary Odd Squad agent.}

Played by: Jack McBrayer

The leader of the Weird Team. A former agent-in-training of Odd Squad turned traitor, he seeks revenge on the organization for not being able to become an agent. Using his Hologram-inator, he leads his team on a mission to prove themselves as more than just a mere ineffective knockoff of Odd Squad and put them out of business for good.

• Adults Dressed as Children: At the end of the movie, he is named an honorary Odd Squad agent and is shown dressed in an Investigation agent uniform. However, it's too small for him, and Oprah comments that Odd Squad only has kids' sizes.
• Became Their Own Antithesis: Weird Tom didn't become an antithesis — he was an antithesis to begin with. Unlike other Odd Squad agents that take their time solving cases and think their courses of action through, he prefers to take a "shortcut", as he so calls it, blasting everything in sight without thinking of the consequences.
• Catchphrase: "Sha-boom!"
• Child Hater: He tends to view children as inferior to adults, which is why the Weird Team is completely child-free.
• Cool Car: He and the rest of the Weird Team have a sleek red-and-white Dodge Caravan that they use to drive around town and help out clients who have been affected by oddness. It's a contrast to both Odd Squad's tiny toy cars, which can only fit one person and drive very slowly, and to the Tube Travel system they use to go from their underground Headquarters to their desired location aboveground.
• Evil Counterpart: To Oprah, being the leader of a team that solves odd things with the use of gadgets. However, whereas Oprah is more benevolent, believing in Team Spirit and solving problems by thinking things through, Weird Tom doesn't believe in teamwork and believes that taking quick shortcuts is the best way to solve problems. In addition, he has "Weird" for a title as a direct contrast to the "Agent" title most employees of Odd Squad have.
  • To an extent, he's also one to the Big O, with the climax of the movie implying that he runs every single Weird Team precinct in the world much like how the Big O runs every single Odd Squad precinct in the world. However, while the Big O is a Pointy-Haired Boss who's also a child, Weird Tom is much more competent when it comes to leading his own precinct, and is an adult.
• Face–Heel Turn: He was an agent-in-training back in 1983 (before Oprah became an Odd Squad Director), having just graduated from the Odd Squad Academy and bearing the name "Agent Om". However, when Oprah disagreed with him on his method of solving cases (blasting everything in sight without stopping to think) and suggested he go back to the Academy for more training, he took offense to it and decided to become a villain instead.
• Gadgeteer Genius: He managed to build a Hologram-inator using a folder of plans for the gadget that Precinct 13579 had stored in a dark room. However, it took him 34 years to do so.
• Heel–Face Turn: Ends up pulling one of these when he inadvertently lets the Daves escape from their room. By the end of the movie, he is named an honorary agent of Odd Squad.
• I Work Alone: He doesn't believe in teamwork, which is quite ironic given that his organization's name is Weird Team (a fact that he lampshades).
  Weird Tom: [to Bradley] You see, I don't believe in "teamwork". I tell my people, "Don't talk to other folks. Don't help other folks." If you have a problem, fix it yourself!
• Manipulative Bastard: When Odd Squad agents aren't playing right into his hands, he's more than capable of manipulating them, slandering them on public broadcast and making sure he and his team gets a jump on them when it comes to solving cases and helping clients. It helps that he's a former employee of the organization.
• Near-Villain Victory: He succeeds in running Odd Squad out of business, if only because the Big O makes Odd Squad surrender instead of trying to fight back. His reign lasts for a month before Olympia and Otis decide to take action and end up working to take back their precinct and restore the organization, which they, along with Olive and Otto, end up doing by the end of the movie.
• Shock and Awe: He has a lightning motif going on, what with the Weird Team's logo being a hand with lightning bolts shooting out of its index finger and his Hologram-inator firing a beam similar in color and shape to a lightning bolt.
• Vague Age: Averted. He was 12 years old in 1983, and the gadget he stole plans for took 34 years to complete. Considering the movie takes place in 2016 (despite the fact the gadget would have been completed in 2017 if it took 34 years), this would make him roughly 45 years old.
• Villain Song: "Something Weird Has Just Happened", a song that's basically one long diss track aimed at Odd Squad.
  "Can't say I blame you guys for trying to be heroes, but maybe you should wait until you grow up."
• Villain with Good Publicity: He constantly steals Odd Squad's thunder and helps out clients long before they can, causing the townsfolk to start admiring him and the rest of the Weird Team. However, it's tarnished when it's revealed that he's not solving problems at all, and is instead merely covering them up.
• Vocal Dissonance: Even as a 12-year-old kid, Tom still has the same voice he has as an adult, with Jack McBrayer providing his voice rather than Sam Ashe Arnold, the actor portraying him as a child.
• What Happened to the Mouse?: Even though he is named an honorary agent of Odd Squad at the end of the film, he never makes any other appearances in the series proper outside of one mention in the OddTube episode "Interview with Olive".

Weird Emily

^{Click to see her in civilian wear.}

Played by: Hannah Simone

Weird Tom's faithful, but submissive, second-in-command.

• Cowardly Lion: While she has no problem antagonizing Odd Squad, she is very cowardly to such a point where she frequents a Curl Up and Cry Room that Weird Team's headquarters just so happens to have as a remnant from taking over Precinct 13579. She is also very submissive when it comes to Weird Tom, always following his orders and never showing any sort of disobedience out of fear of the consequences.
• The Dragon: Is this to Weird Tom. However, it's left ambiguous if she serves this role to the Weird Team in general.
• Heel–Face Turn: Pulls one at the end of the movie.
• Prim and Proper Bun: She sports one on her head.

Odd Squad: World Turned Odd Characters

Odena

Played by: Amy Khou

Odd Todd's right-hand agent in the Bad Future.

• Asian and Nerdy: She is Asian, wears glasses and braces, and is shown to have some incredible capability as Odd Todd's second-in-command (though not without her dumb moments).
• Canon Foreigner: She never appears in any other franchise material outside of Odd Squad: World Turned Odd, and isn't even an employee of Precinct 13579 in the present day.
• The Dragon: Out of the agents in the Todd Squad, she serves as this to Odd Todd in the Bad Future.
• Gadgeteer Genius: Her first appearance in the movie shows her attempting to fix a piece of metal, presumably from a gadget, using a blowtorch. This is how Oona, returning to her Lab after time-traveling, manages to run into her and realize that something is very wrong.
• My Master, Right or Wrong: Zig-zagged. She shows a few signs of defecting from the Todd Squad, especially when she finds that she has been afflicted with oddness in the form of her face glowing green whenever she tugs on her right earlobe. However, in spite of wanting her oddness fixed, she remains loyal to Odd Todd and has no problem antagonizing Oprah and the others along with him.
